Maybe, but are there statistics to support that? People point to things like the U.S. lagging on indicators like maternal and infant mortality, and life expectancy. But if you dig into the data, non-white Hispanics (which have a 20% uninsured rate) have similar maternal and infant mortality to whites (which have only a 5% uninsured rate). And hispanics have significantly longer life expectancy. American hispanics, despite widespread lack of insurance, live as long as people in Denmark or Sweden, who have comprehensive universal health care. Moreover, Asian Americans, which have a slightly higher uninsured rate than whites, live the longest of any people anywhere in the world. They live 2-3 years longer than people in Hong Kong or Japan. (And trust me, there is no secret health system for us Asians. We have the same shitty UHC or Cigna insurance everyone else does.)

There is a lot of rhetoric in this area, but few firm conclusions to be drawn.
