Americans complain about taxes more than perhaps any other people from a rich nation, but we frankly don't pay that much. The OECD average is about 35% of GDP. The UK pays right about that. The US pays ~27% of GDP. And of course even with that relatively small amount of revenue, a lot of it goes to uniquely American spending schemes like defense or NASA, both of which are vastly better funded than their European equivalents. So it's really not all that surprising that lots of other stuff doesn't get funded much.

That being said, the homeless rate in England and the United States is the same ( https://en.wikipedia.org/wiki/List_of_countries_by_homeless_... ). Do you see a similar resistance to supporting people there?
