The working-class dollar does more work.
Give a dollar to someone living paycheck to paycheck and it gets spent — at the grocery store, the mechanic, the local everything. Give it to someone already rich and it mostly sits, bidding up the price of assets they already own.
This isn't a moral claim, it's an accounting one. Economists measure how much of an extra dollar a household spends — the marginal propensity to consume — and it falls steeply as income rises. So the same dollar generates more near-term economic activity when it lands with people who spend it than when it lands with people who save it. By that arithmetic, an economy runs hotter when the marginal dollar reaches the working class. It's the demand-side reason the revenue plan and the income-security plan point the same direction.
What this page argues
The marginal propensity to consume — the share of an extra dollar a household spends rather than saves — is high for people who live paycheck to paycheck and low for the wealthy. That's one of the most stable findings in empirical economics. It means the near-term boost to spending, output, and jobs from a given dollar is larger when that dollar reaches lower- and middle-income households.
So the distribution of income isn't just a fairness question; it's a growth-of-activity question. A dollar recirculating through working households does more visible economic work than a dollar parked in a portfolio. That's the demand-side companion to taxing wealth like work and to a strong income floor: put the marginal dollar where it moves.

The working-class dollar does more work.
Give a dollar to someone living paycheck to paycheck and it gets spent — locally, fast. Give it to someone already rich and it mostly sits. Not a moral claim; an accounting one.
The record, claim by claim
The marginal propensity to consume falls with income: poorer households spend a much larger share of an extra dollar than rich ones.
FACTThis is one of the best-established regularities in economics, from Keynes's original formulation to modern micro-data. When households receive an unexpected dollar — a tax rebate, a stimulus payment — low-income and liquidity-constrained households spend a large share of it quickly, while high-income households save most of it. Studies of the 2001 and 2008 tax rebates (Parker, Souleles and colleagues) and bank-transaction data (JPMorgan Chase Institute) find the same steep gradient. The size of the marginal dollar's spending punch depends on who receives it.

Because of that, fiscal help aimed at lower-income households has a larger 'multiplier' than tax cuts skewed to high earners.
PROBABLY TRUEIf lower-income households spend more of each dollar, then transfers and benefits targeted at them recirculate through the economy more than tax cuts concentrated at the top — a bigger 'bang for the buck.' The Congressional Budget Office and independent analysts (e.g. Moody's/Zandi multiplier tables) consistently rank aid to the hard-pressed (unemployment benefits, food assistance, direct payments) above high-end tax cuts. We grade this PROBABLY TRUE because the exact multiplier magnitudes are contested and state-dependent — larger when the economy has slack, smaller near full employment — but the ranking by recipient is robust.

A rising share of the wealthy's marginal saving flows into existing assets, bidding up prices rather than funding new activity.
SOME SMOKEThe popular version of the argument — dollars to the rich 'just inflate the S&P' — points at something real but hard to pin down. High-income households save more, and in a low-interest, 'savings-glut' environment much of that saving chases existing financial assets, which is consistent with elevated valuations and rising wealth-to-income ratios. We grade this SOME SMOKE, not higher: the direction is plausible and supported by the savings-glut and asset-valuation literature, but cleanly attributing asset-price inflation to income distribution specifically is genuinely difficult, and we won't overstate it. The load-bearing claims above don't depend on it.

Reducing inequality has not, on the balance of evidence, come at the expense of growth — and may support it.
PROBABLY TRUEThe old fear that helping the bottom must slow the top is not what the cross-country evidence shows. The IMF (Ostry, Berg and colleagues, 2014) found that lower net inequality is robustly associated with faster and more durable growth, and redistribution — except at extremes — is broadly benign for growth. The OECD (Cingano, 2014) reached a similar conclusion. We grade this PROBABLY TRUE because macro-growth attribution is always contestable, but the 'equality-vs-growth tradeoff' is far weaker than the standard objection assumes.

The counter-cases, and why they fall short
- “Saving isn't idle — it funds investment that grows the economy.” The strongest counter, and true when capital is the binding constraint: savings finance the machines, buildings, and research that raise long-run output. It falls short when the binding constraint is demand, not capital — the post-2008, persistently-low-rate world, where a savings glut signals too much money chasing too few productive outlets. In that regime the wealthy's extra dollar disproportionately bids up existing assets; the working household's extra dollar creates the demand that actually pulls new investment forward.
- “Velocity is just an accounting identity — you're overreading MV = PQ.” Fair as far as it goes, and why we don't rest the case on monetarist “velocity.” The load-bearing claim isn't the residual V in a quantity equation; it's the separately-measured marginal propensity to consume and the fiscal multipliers built on it. “Velocity” is the memorable label; the evidence is the spending data.
- “Redistribution shrinks total saving and hurts long-run growth.” Flawed on the evidence: the IMF and OECD find lower inequality is at worst neutral and plausibly growth-supporting, not the tradeoff the objection assumes. Human capital and demand stability are inputs to growth too, and both improve when the floor is higher.
Where the evidence is strong, and where it stops
- The MPC gradient is rock-solid; the multiplier sizes aren't. That poorer households spend more of an extra dollar is about as settled as applied economics gets. Exactly how much extra GDP that buys — the multiplier — depends on the economy's slack and the central bank's response, so we treat magnitudes as ranges and lead with the ranking.
- “Velocity” is a metaphor doing honest work. We use it as a hook, then cash it out into MPC and multipliers so nobody mistakes a monetarist identity for the argument. The claim survives the translation.
- Near-term demand ≠ long-run growth. This page is mostly about the near-term activity a dollar generates. The long-run picture depends on what the money funds — which is why it pairs with the investment spoke, where the highest-return uses live.
Put the marginal dollar where it moves
This is the engine under two other pieces of the Pragmatic Policy plan. It's the demand-side reason to tax wealth like work — a dollar compounding untaxed in a portfolio does less real economic work than one recirculating through households — and the reason a strong income floor is not just humane but macro-economically productive. A government trying to maximize wellbeing within its limits should route the marginal dollar to where it gets spent, not where it gets stored.
Questions worth taking seriously
If spending is so good, why does anyone say saving matters?
It matters enormously — in the long run, saving funds the investment that raises what an economy can produce. The point here is narrower and near-term: for the same dollar right now, spending creates more immediate activity and jobs than saving does, and poorer households spend more of it. Both things are true; they operate on different horizons, which is why this spoke pairs with the investment spoke.
Isn't 'money to the rich just inflates the stock market' an overstatement?
Partly — which is why we grade that specific claim SOME SMOKE, not fact. High earners save more, and in a low-rate world a lot of that saving chases existing assets, consistent with high valuations. But cleanly proving that distribution specifically drives asset prices is hard, so we don't lean on it. The solid claims — the MPC gradient and the multiplier ranking — carry the argument on their own.
