> Many Europeans won’t drink the milk here in the States because the quality tends to be much lower, due to feed/living conditions for livestock. Garbage in = garbage out.

If you have the time and money, I found the opposite to be true.

The average quality of products like bread and meat is much lower in the US than in Europe, but in the US I have the option of going to some high end shop or bakery and get stuff that is much better than I can get here in Europe. In Europe things are extremely uniform. (Yes, I realize that Europe is a big place and I am generalizing somewhat.)

Good cheese is very hard to find in the US though. Speciality shops are rare and even there you have much less options.

When I go to the US, on the first day I am very saddened by the "bread" and milk I can find, it's just awful, but quickly I go to the good shops and get the good stuff.

When I come back to Europe I am saddened again because now I can't get the good stuff anymore, no matter how much time and effort I put into it. That's why now I bake my own bread here in Europe.

I spend a large proportion of my time in the US, and I found that this phenomenon generalizes to many products. For many products the US average is worse than the European equivalent, but in the US there's a much broader distribution of quality, and the high end tail of the quality spectrum is usually in the US. Of course this quality comes at a cost.
