There are plenty of places to buy good meat in the US, but many people don’t bother looking. I live in a small town, and we have a butcher shop that works with local farmers and provides everything you listed above. You’re correct about the threat that Walmart and other national chains (Krogers is the worst, honestly) that have “out competed” small businesses so they can put the cheapest three meats of the lowest acceptable quality in front of people at “value prices”.
