My point is if you're in the bottom half, being white won't be perceived as privilege by those struggling, and you're not going to elicit much sympathy from those people, especially if you're implying they're "losers" who couldn't make it even through they're white.
The Democrats have put race before class, partially because upper middle class white liberals want to preserve advantages for their children so they grant privileges to primarily the children of the black upper middle class at the expense of ALL working class people.So diversity is a cheap way for them to signal virtue without imperiling their social advantages.
Look who the Democrats are appealing to: college students, minorities and women on abortion. While they'll take populist stances against corporations, promising not to raise taxes for people making less than $400K? In other words, all but the top 1% in income - meanwhile running deficits that ensure higher interest rates in the future.
401Ks, gold plated health insurance not treated as income and so on all benefit the top 5-10%.
Even when the Dems do something for the working class (expansion of Medicaid and Obamacare, more aid for community colleges) they do a lousy job of marketing it.
