I have heard this suggestion before in the context of overcoming suboptimal risk intolerance (like right after a crash) but for it to work you would have to derive the tax revenue somehow from people who were not spending money. That's one thing I've never understood about Keynesianism.

Government spending isn't immune from opportunity costs. If fewer players receive all the money to provide fewer more expensive goods and services, then revenue may be flowing through the national coffers but the money doesn't cover what the government wants to do.

Unless you forgot a /s, in which case (thumbs up).

- All spending is equally productive

- All tax comes back efficiently

- Big contractors = better fiscal outcomes

In reality, value-for-money, fiscal responsibility, and economic multipliers are more nuanced. More spending doesn't necessarily mean better outcomes; how it's spent matters enormously.

Assuming that government spending is inherently productive is a deeply flawed view. Every pound the UK government spends is a pound it had to tax, borrow, or inflate.

If you were to look at the NHS's EPR procurement, you'd see hundreds of millions of pounds over a decade spent on American software.
