I think a huge part of the problem is that as a society we're okay with this. It makes me sad when I think about it- I'm smart enough to acknowledge the problem but too ignorant/stupid/afraid to be a part of the solution.
Like 75-90% of them are gone now, either as $600-700/mo rentals, or empty lots (many of which people are now farming).
The only house still left on my block in Brightmoor is my neighbor's house and his house looks like it's falling down, too. He's still living in it as well because all of us were just barely making it.
I wish I made FAANG money. After taking care of my own debts I wanted to buy our build as many houses for my block as I could and then just let people stay in them no matter how much it costed me ("a fool and his gold are easily separated" and whatnot). I know it's stupid but the one thing I always wanted growing up was just for someone- anyone- to come in and say "we can't treat people like this" and help without considering the business value of helping. So many people spend so much time thinking about how to help (rightfully so) that nobody ACTUALLY ends up helping.
Still, I do think the US (and the world) should really put the "Golden Rule" as a top priority. So many problems would be non-issues if we did!
