in PA it's Section 8 housing that is destroying the inner ring suburbs, illegals or not.
Pittsburgh area is not attracting immigrants or young people because it lacks a dynamic economy (relatively speaking). Therefore, the landlords have no recourse but to either rent cheaply or get the extra money that comes with Section 8 housing.
I grew up in one of the first 'burbs outside of Pittsburgh. Public Transportation killed it.
Projects by any other name. I don't want a return of the tower blocks but isn't it amazing how the government provides 'affordable housing' (whatever that means - does affordable mean free?) and then the ungrateful recipients trash new buildings and entire neighborhoods within months, even weeks? I literally laugh out loud every time I hear the term 'white flight.' It is purely the human survival instanct + gainful employment + a desire to avoid squalor and lawlessness. And my black and Asian neighbors think so too! Urban sprawl? They can keep the 'urban' part.
