That's the real problem, how do you figure out what caste you're in.
If I'm a doin OK white guy, do my kids get to be down and out if they work to put themselves through school?
And what about my put upon grandfather? Don't I get a bump up for him?
And what do you do about the fakers?
I knew a rich old Texan, who owned several banks, lots of cattle and big oil interests who would put on his dirtiest overalls and look as scruffy as possible when he went to the doctor, "Just so he don't overcharge me."
