There’s a lot of incredible American- made cheeses, usually from more local cheese makers. Wisconsin and Vermont are the most fampus for their cheeses, but every state probably has good cheesemakers and there are some pretty good national brands. But the main cheese section at your typical grocery store is mostly just mass-produced cheap cheese that is probably more what you’re referring too, which is fine for most uses (e.g. cooking) but eaten alone i would describe as perfectly fine but not great. A lot of grocery stores have a nicer cheese section, but it’s usually in a section of the store more with other small bites.
