I’m willing to bet that the more solidly Democratic your parent is, the more likely it is that your opportunity is lower.
Stupid parents do set a child back, but luckily the child has free will to become conservative and do well in life.
I am afraid it is not true.
A lot more “Affluent People” (doctors, teachers, professionals like scientists/engineers, etc.) are voting Dems, or at best socially left leaning. (I don’t have the statistics, but remember something in the high 60 to 70%.)
Their children are definitely not lacking opportunities. And maybe they prefer it that way. Gotta keep %^$^&s on the plantations, you know!
