Earlier quoted context omitted.
>major dental or surgical needs that are today fixable with little fuss I guess perhaps that's true in some countries, but not for the US. People put off major medical needs for years and even decades to wait until they can get on medicare. Dental issues are even worse. Yes, the availability of the treatments is nice, but the majority of people are deeply stuck in modern society to have access to those treatments.
Truly? You're comparing problems in access to smooth insurance coverage among a certain percentage of the U.S. population to a total lack of existence for anything resembling modern medical and dental care in the world of the pre-industrial era? I could make a large list of all the ways in which this comparison is laughable.
You should make a list. I would find it very helpful. The people claiming the world progresses in a single direction will eat their words one day.
