That is really a myth to be fair. The U.S spend 3.4% while having a larger GDP per capita than the Netherlands and we spend 1.4% on defence. also a lot of our money we spend on defence doesn't come back in our economy but yours does and even makes money abroad. On infrastructure the U.S. is not as dense as we have so it becomes more expensive to have nice roads everywhere. We are also the europort so we need to have good infrastructure to get the goods to Germany and the rest of Europe. hospitals are also privatized here as well but more regulated than in the U.S. Even we need to regulate more still but that is an ongoing battle that will go on forever anyways and will become more strict or more loose with each time a political party is in charge.

I follow the U.S. politics a bit but they always seem to make a lot of noise for big changes and nothing happens afterwards because it is to big to change in one go. America should do it more slowly and incremental and become a tiny bit less populist on both sides democrats and republicans. We also have our problems to be fair and are not perfect at all.
