> I cannot wait until this whole place is gentrified and cleaned up
The thing you are complaining about Are The Consequences of gentrification. They are the output of the process. The system you advocate for produces that which you are complaining about.
It's not going to be "cleaned up". This is what that process yields. Gentrification creates more "cracks to fall through" and so more people "fall through the cracks" through the financial consequences. These issues are the consequence of it - that's why it happens everywhere things are gentrifying.
These stratifications produce slums, favelas, cantegrils, gecekondus, barrios, karton siti, paraggoupoli, zopadpatti, baraccopoli, putri, perkampungan kumuh... there's words in almost every language for this phenomena. Policies are machines. They produce things.
This is the outcome of the process, globally, for centuries. You can not possibly get to your goal through that method. It does not work.
I know how alluring the logic is, but like counterintuitive math and science, the obvious solution does not work and we need to stop pretending otherwise. Reality doesn't give a damn about personal belief and stubbornness in systems that don't work. You can't will a wrong answer into being right.
It's the material reality.
