No, Dems will never give up the racism and inequality trope...too much power and money in keeping their favored constituencies poor and ignorant.
For me, the classic example is always government schools:
If a school is turning out well-educated, well-behaved students, and then asks people to greatly increase the budget, the response is likely to be: "Nope. You're doing fine."
But if a school is a disaster, with poor test scores, lots of fighting and drugs, and then asks people to greatly increase the budget, the response is likely to be: "Have millions! Hire more staff! What else can we give you??"
There is no incentive to fix any problems. If you do a BAD job, the money just flows to you, endlessly.
That assumes that 'racism' is eradicable. I am about 100% certain it is not particularly since 'racism' is largely in the eye of the beholder and is almost always defined by the user of the term.
I think this picture illustrates well why it is not eradicable. Just as more recently the whole Ferguson fiasco has and a list a mile long of other racial events.
