It's perfectly possible to buy decent chocolate in the US. Eg Lindt and Ritter Sport seem to be widely available. (They are far from the best chocolate, they are just decent-enough brands that I remembered at the top of my head, and could verify with a quick web search are available in the US.)
How toxic is that meat actually? What are your sources? How do you know it's more of a problem in the US than in Germany? (Americans like to complain about their products. But we get American beef here in Singapore, and it's generally ok. Typically not as good as the Japanese or even Australian stuff, but good enough.)

The stories I heard are rather the opposite: the political and regulatory backlash against the alleged 'opioid epidemic' has been so bad, that it's hard for people who legitimately need painkillers to get a prescription.
I suspect the US is a big country, so both accusations can be true at the same time. Even if the problem is tiny in relative terms, because of the size of the country, in absolute terms you will find plenty of cases of both failure modes.
