Arguing as if there were never occasions of large-scale unemployment in which spending on public works doesn’t “crowd out” a like amount of private employment isn’t a good look for pro-market economists.
Keynesian stimulus doesn't magically create prosperity from thin air. It redistributes existing wealth from productive citizens to those with the best lobbyists and campaign contributions.
When Congress passes a trillion-dollar "infrastructure" bill, you don't see bulldozers materializing from the ether. The government pulls capital from entrepreneurs who would have built factories, funded startups, or expanded payrolls. Instead, that money flows to Halliburton, Bechtel, and whatever construction firm hired the right former senator as a "consultant." The politically connected get guaranteed profits while you get higher taxes and inflation.
The process works like a sophisticated laundering operation. Politicians promise jobs and growth while funneling taxpayer dollars to their cronies. Boeing gets defense contracts. Goldman Sachs underwrites the debt. Big Tech companies score "green energy" subsidies. Meanwhile, small business owners struggle with regulatory compliance costs and compete for the remaining scraps of capital.
Free market economists identified this wealth transfer mechanism decades ago. Keynesian mythology persists because it serves powerful interests. Politicians love spending other people's money. Corporations love guaranteed returns. Wall Street loves bond issuance fees. The only losers are productive citizens who fund the whole charade.
You can spot this corruption every time politicians claim stimulus will "create jobs." Jobs doing what? Building bridges to nowhere? Manufacturing solar panels that cost more than the energy they'll ever produce? Productive jobs emerge from genuine consumer demand, not political theater. Everything else just moves money from your pocket to theirs.
