Our tax dollars fund more corporations than other countries. The military spends so much because they pay private companies for their equipment, which is sold at inflated costs because they can. The US spends a shit ton on health care because private companies inflate their prices because, again, they can. The government/insurance companies don't even pay the full price that's listed on the bill, but they still use the original numbers.

You can't compare our spending to other countries. The US spends more because they pay inflated prices. Citizens spend less because we can't afford to get health care.
