Beats me on what do they spend those taxes

It's spent on what is by far the most powerful, expensive, and expansive military in the world, with funding about equivalent to the next ten militaries combined. All of Europe barely has any military spending by comparison; NATO is almost entirely propped up by the US military industrial complex. If US foreign policy wasn't so doggedly imperialist, we might have room for some healthcare.

That's not even getting into how medical corporations in the US are more or less financially unrestrained and allowed to make as much money as they want, paired with an insurance industry with the same conditions, and both industries becoming more and more consolidated, with all the big players participating in the stock market. The result is a race to the top in which everything is made far more expensive than it needs to be in order to please shareholders. In this environment, spending government money on US healthcare is substantially less efficient than the same spending would be in a European country.

Correction of these markets, as with housing, is likely to be financially devastating to the economic elite, but also critical to the prosperity of real people in this country.
