Austrian vs Keynesian vs MMT

Should money be scarce and hard, or flexible and managed? Three schools of thought give sharply different answers — and the fight between them decides how much money gets printed, who benefits, and who pays.

Austrian

Money should be hard and beyond government control — ideally a commodity like gold. Printing money distorts the economy: cheap credit fuels booms that inevitably bust. The cure is sound money and letting markets, not central planners, set interest rates. Deeply sceptical of central banks. This is the intellectual home of most Bitcoiners.

Keynesian

Markets can get stuck in slumps, so government should actively manage the economy — spending and cutting interest rates in downturns, easing off in booms. A little inflation is healthy; the real enemy is unemployment. This is the mainstream view that runs most central banks and treasuries today.

Modern Monetary Theory

A country that issues its own fiat currency can never “run out” of it — it can always print more, so it’s never forced to default. The only real limit is inflation. Government should spend freely to achieve full employment, and use taxes mainly to cool the economy, not to “fund” itself. The most permissive view of the three.

The crux of the disagreement

They’re really arguing about that dial from earlier lessons — hard money versus flexible money:

Austrians trust rules and scarcity, and distrust the discretion of officials to print.
Keynesians trust skilled managers to smooth the business cycle with that discretion.
MMT pushes the flexible view furthest, treating the printing press as an ordinary policy tool bounded only by inflation.

This isn’t a dry academic debate — it decides whether your savings are protected by scarcity or eroded by expansion. Every stimulus package, bailout and interest-rate decision is one of these worldviews winning the argument for a while.

The unanswered question

Austrians make a powerful case for hard money — but they’ve always faced a practical objection: gold, the hardest money we had, is hopeless for a fast, global, digital economy. You can’t email a gold coin. For most of the 20th century that objection looked decisive, and it’s the note this section ends on.
