If Democrats care about the poor or minorities or both, why do they keep making decisions which hurt both so often?

Flooding the job market with poor low skilled foreign workers depresses the wages and advancement opportunities in career fields statistically more likely to be held the poor or minorities. Flooding the housing market with people who have to live somewhere raises the price of apartments and houses beyond the ability of the poor to pay, even with sluggishly adapting government assistance. This is a competition landlords win and renters collectively lose. I can go on later, but this is a good start while I’m at work.
