I was so poor growing up [that we had to eat dust bunnies that we swept out from under the bed] but back then we all had health care. Health care only became unavailable and too expensive after Medicare was legislated in the 1960s.
I grew up poor too (those dust bunnies aren't bad if you have a few carrots and some cornbread stuffing!) in probably an even more rural landscape, and we did not have health care beyond what our mothers could conjure up out of Vaseline and a little coal oil. There was no doctor in our community, no clinic, no nurses, nothing. Which is why so many farmers were visibly maimed by scars and breaks and lost limbs. Stepping on a rusty nail in that country was about as dangerous as snakebite, because you probably weren't going to reach a doctor with a hypodermic before tetanus set in.
Foxx's rosy "everything was fine before there was a social safety net" is just so much buffalo dust.
