Not 100%, but they definitely didn't help marginalized groups. Poverty is a monster that devours and destroys whatever it touches and it can be caused by poor personal decisions. However, the moves from the post WWII housing lenders and government of the time manufactured much of the poverty that affects the cities in America. Baltimore just looks harder hit because of the city's racial makeup. The practices I mentioned (redlining, blockbusting, etc) were designed to primarily target blacks. In a majority black city, the effect is seen in greater detail and in a wider span.
