My mother is German. I have lived in Europe. I will suggest that the fact that you are European will likely inoculate you against a lot of worst case scenarios because normal American practices that promote disease and injury simply are not part of your culture.

Diet plays a very large role in disease. Immigrants don't typically start living off of fast food burgers. They continue eating largely like they did at home.

Europeans tend to drink responsibly. They have wine with dinner or drinks with friends at a pub. The US has rampant addiction problems killing people.

If you don't plan to abandon your current healthy lifestyle habits, suddenly start drinking and driving just because you set foot on US soil and otherwise abandoning all common sense as you have known it for your entire life, you probably don't need to fear that taking an American job will trap you in American medical poverty hell with no hope of escape.
