That’s because the American health care system is by and large run as a for-profit enterprise, and that kind of thing as we well know always eventually devolves into a race to the bottom to maximize profits at the expense of everything else until it collapses.
But in this case, “at the expense of everything else” is not churning out lousy hamburgers or making gaming keyboards that break 2 days out of warranty. Rather, people don’t receive competent health care, don’t receive care soon enough, or just don’t receive care at all and in some cases die. All for a buck.
I know that’s not necessarily the correlation the article is trying to make with its survey, but I’ll bet you a nickel it’s the majority of the root cause of the outcome in any case.
