The good American cheese is not in fact "1%-er bullshit". Have you gone to a restaurant like McDonalds? You have eaten the better stuff, which comes pre-stacked in a large block. It is certainly much better.

Idk what that other guy is on but our grocery deli has American cheese they slice themselves, it's not much more expensive than craft

Kraft has “Deluxe American” cheese slices that aren’t individually wrapped and have a better flavor and texture.

I think by Good American cheese they meant something more like this:

It is very much a different thing than Kraft Singles, you can get however much or little of it (or various competitors) you want anyplace that has deli meats, and the per-pound cost is not that much more, last I checked.

Although some kinds of cheddar might be made in the US, I don't think Vermont Cheddar is what anyone usually has in mind when they say "Deli American Cheese."

I've had no problem getting a good melt on burgers with "good" American, FWIW.

Most block cheeses with a good fat and moisture content will melt well when shredded off the block right before you intend to use it. The pre-shredded or pre-sliced stuff has additives like starch in and on it to stop it from sticking together in the package and melting during transit, which prevents a good melt. Get yourself a cheap rotary shredder from Amazon (they're like $20, mine never stays clean because I use it like every other day) and see for yourself.
