It's not quite that bad. For example, the Boston area is arguably as good or better than those two cities. And some higher-income relatively small town/rural areas are pretty decent. But it definitely becomes a bigger consideration as you get older--although you can of course get unlucky at any time.
It’s a problem in the medium sized cities too? Because many of the smaller rural facilities are being closed down (often in the wake of for-profit buyouts), and then all those displaced patients overrun the remaining facilities in surrounding towns.
