I agree with the gist of this video which is sort of unexpected after reading the title. It's basically saying Americans spend more, in terms of taxes and so on, for less than any other country (especially when you include health care costs).
The problem imo is the government wastes a tremendous amount of money and is very inefficient. Things like lobbying, honest graft, political favors, special programs and so forth, that shouldn't be allowed at all, make it so congress's interests, having too much motivation for their own personal profit, don't align with the people well enough. Need to get rid of all of it.
There's also a myth that any spending is good. Not that all spending is bad, don't conflate that, but there is way too much wasteful spending. For the amount we already spend including health costs, all taxes federal, state and local (or close, I'm guessing here, need to look at everything as a % of GDP including health costs) we could afford the infrastructure, health care, safety nets and so on, comparable to Europe or Canada. We already spend twice as much as most countries on health care in terms of GDP (about 18% US vs about 9% in Europe), so that's a big one.
