but what about all the drugs, toxins, vaccines, air pollution, water pollution, etc. that 'higher powers" have their hand in?
You don't even have to go that far. The US has high taxes on the importation of healthier versions of things. Even if we look at things we usually consider unhealthy. Cane sugar and chocolate are heavily taxed so that we have to use corn syrup and keep the product domestic. In other countries chocolate is a lot tastier, higher quality without the crappy preservatives, and in all foods the use of certain sweeteners over our high fructose corn syrup and similar products results in a feeling of satisfaction, even fullness, you don't as easily get in US foods. It also reduces diabetes compared to sweeteners made in the US or allowed a lower tax. There are endless examples of these things from junk food to healthy meals that aren't as healthy as they would be elsewhere. I don't think you can blame anyone for any health problem except maybe things like smoking. Even alcoholism is a product of our society, it's much rarer to drink to such excess in other countries, and addiction and/or depression problems that may have everything to do with genetics and not lifestyle choices.
Something needs done for healthcare but I don't know what. I owe $2000 in medical bills and require $900/month for meds. All for genetic problems that resulted in more problems because of crappy doctors and a few injuries that were complete accidents growing up. With good insurance and paying portions of what I owe I ended up with at least $2000 in debt collection. Right now I don't have insurance. I didn't go to a doctor for the toe I'm pretty sure I broke and I'm having to rapidly get off a med that would cost far too much out of pocket. We applied for help from various angles but mostly were denied or have to jump through hoops before it takes effect. They don't even look at medicaid applications for 45days. By then I might be $1800 in debt for medications that I can't just quit cold even if things would be fine without them. If we turned it all over to state or federal money though I question if I would even get the meds I need. I'm sure doctors would have to justify costs to a greater extent and my combo of meds is first off nearly all off label use and secondly medications that are normally not supposed to be mixed together. If some state system is looking at what is being prescribed they probably would not see the justification. With insurance they mostly do what the doctor says.
