Blame the Democrats, their "Great Society" and the personal ignorance and slothfulness of people. As for "class", it is earned and not given. It's not a birthright but the product of behavior.
This should be known by all but is routinely ignored by those that the Democrats feign so pusillanimously to "defend". There are plenty of "white trash" people too, you know. But Democrats affix "class" primarily to skin color and why? To assuage their libtardian white guilt and all at the expense of the truth.
And the truth is that the "Great Society" failed because it failed to promote honor, hard work, family and so much more instead replacing those with welfare checks and the promise of payment for a vote.
Jealous people will envy only those they consider their betters and demand equality without working for it. Equal under the law, yes. But not under the sun.
Another thought to consider is that if you continue to fill a cage with rats, no matter the color of their fur they will ultimately turn on one another.
