Trump's campaign plays well to the inner city for so many reasons. Now whether they will realize it or not remains to be seen. But if the inner city African Americans think that Hillary's open border policy is going to help them they can think again.
For example lets say that a company has a low skill job. Do they give that to an American Citizen with some run ins with the law? or do they give it to the new immigrant who you can't background check so looks completely clean on paper?
The hiring manage will give it to "new immigrant" (formerly illegal alien before Hillary changed to open borders). That way if anything should happen that's bad with that employee they can say they did their due diligence as best they could and they are off the hook as far as liability is concerned.
Even in the suburbs Trump's plans for the economy work to the advantage of every young adult that doesn't really know what they want to do for a career. It used to be that if you got out high school didn't know if college was for you, you could find a job as a janitor at a big company. Just by being in that company during the day you saw who were the movers and shakers were. Who were putting in the extra hours to get ahead. You could talk to them find out why they chose there career path and ultimately if you had some ambition could start to fashion a path for yourself.
Today you get a job with fast food chain X, find a roommate, talk to no one except others in your predicament. How do you ever get ahead?
I could go on and on. I know that industries change and some of that plays a role as well but there are so many young people who used to be given a leg up in life and now are just being left behind.
In other words, your post proves the American people are dumber even than we thought.
