Your comment about the US tax rate is misguided though. While we might technically pay less than some European countries (not much less, in some cases), we also receive a lot less in return.

A vast amount of US tax dollars go towards social security--a creaky, shuddering retirement plan that many expect will collapse before they ever benefit from it--and defense. When ~32% of your paycheck evaporates with no clear benefit like those enjoyed in European countries, it makes sense to complain.
