Because they’re comfortable living under fascism.

The concentration camp was never the normal condition for the average gentile German. Unless one were Jewish, or poor and unemployed, or of active leftist persuasion or otherwise openly anti-Nazi, Germany from 1933 until well into the war was not a nightmarish place. All the “good Germans” had to do was obey the law, pay their taxes, give their sons to the army, avoid any sign of political heterodoxy, and look the other way when unions were busted and troublesome people disappeared.

Since many “middle Americans” already obey the law, pay their taxes, give their sons to the army, are themselves distrustful of political heterodoxy, and applaud when unions are broken and troublesome people are disposed of, they probably could live without too much personal torment in a fascist state — some of them certainly seem eager to do so.
