Because low income anywhere (rental area or even just low income suburban areas) typically has a population that is less able to invest into their area (in time or money), and historically has shown that they seek an extractive relationship with their environment rather than invest in it.

Haha "extractive relationship" come on man. Poor people aren't vampires, they need to be resourceful in their environment to survive.

Are you joking? Poor people are the exploitative ones? That's just entirely false

The entire basis of capitalism in the US is that the work of the poor is exploited by those with the capital to build factories and businesses which extract labor and resources from the poor people

That's why they can't invest. You have it entirely backwards

Exactly. Most of a poor person's income will be spent locally every paycheck. Higher income, more is saved or sent offshore etc
