Well, carry on, then.
Leave it to
@Farm Boy for the "private investment crowds out government spending" take. I agree, but on the caveat that you started with the caveat. Uber lost money for years, all the backs of investors, who knew it was losing money, and still wanted in early, even though they were going to lose money, too. But they had to do something with their money, their too much, trickle down investment money. So inefficient. As long as their investments exist, the political will to put the government into the same space is limited. And that's where the crowding out happens.
Normally the theory is government spending crowds out private investment. It's a purely economic argument, from the perspective of "if we already have full employment, and we have the government spend on XYZ, then that spending crowds out the private sector from buying the same XYZ". It's tautologically true in its abstract form, as long as the government gets to buy first or bid highest.
But it's dubious in the real world. The private sector underinvests, and so increased spending often leads to simply more economic activity. So instead of a displacement of supply, it's an increase.
So then returning to theory, from the real world, you would think to get the best of both we would just have government spending with relatively low taxes.
But you are arguing that the town halls up through the Senate floors, and in the Senate floors where it matters most, they won't spend an extra government dollar when they can spend 3 dollars on tax cuts for their friend's to do 50 cents worth of quality in the same space. And that the crowding
a) isn't economic but political
b) comes from the private sector crowding out the state
b) driven by what people see already being done, and don't want to interfere with
And this, my friends, is why economics never mattered did it, starting from the very top of the post.
Farm Boy I think you're right. It might not be how it works, but even then, it's how it works.
