Most homeless people have employment lapses that make it hard to find work, even with an address and fresh clothing. Aswell as possibly still having debts that led them to lose housing in the first place.
In other words, $7,500 is a great start, but as you said, $7,500 doesn’t go far with recent cost of living inflation. And as I mentioned, getting back on your feet isn’t easy because employers aren’t quick to hire the recently homeless.
