Lyndon Johnson does not belong in this thread. That man was Lower Middle Class if that word ever meant anything.
Nor does Garfield. Or Reagan. Or Nixon (though this is very much about attitudes instilled, not income raised on.)
Emotion echoed.
Oh yeah, Andrew Johnson is the winning answer.
Garfield was born in a log cabin
That was kinda in vogue at the time.
Quite. The working class couldn't afford real log cabins. (Lincoln was born in one, but spent most of his childhood in something well below that standard IIRC.)
That sounds about right. His father owned a couple of farms, but they weren't successful enough to provide a comfortable living.
