No, talking to one homeless person out of 123000 isn't evidence ding dong.Talking to a homeless person, and listening to every bad decision they make isn't evidence!?! You sound like a tRump supporter now!
And why does no other developed country have this problem? It's because we feed them! We grow them!
And your answer is wrong. Other countries have much much better safety nets and they don't have a homeless problem. Try again.
