It's a direct answer to "Also, please explain why impoverished minority communities have not vastly improved regardless of the constantly increasing money tossed into welfare programs."

Food assistance, subsidized housing, and monthly cash payments are only really short-term stabilizing tools. For that they can be useful, but those systems are not designed or equipped to vastly improve the wealth and self-reliance of impoverished communities.

The key word in "impoverished minority communities" is "communities". Good schools, grocery stores, street maintenance, good transit, good jobs within driving distance, fair lending (and honestly lending practices designed to fix the damage of generations of unfair lending), vocational training, job placement assistance, enforcement of building codes on landlord-owned buildings, stable utility infrastructure including broadband Internet, and other things stable, wealthier communities take for granted are necessary to have a stable, flourishing community population.
