A YouTuber conducts an experiment worth seeing. A homeless man is given $100 and then followed to see what he does with it, then confronted and questioned about it, including how he came to be homeless. It really is worth a look.
Let me anticipate a few valid responses. Not all homeless people are like this guy. Quite a few are dealing with serious mental problems. Some invent a moving story to con people into giving them money. There have always been fake beggars. I don't know for a fact that everything the guy in the video says is on the level.
But on the other hand, look at his actions. The filmmaker says he has a lot of additional footage that suggests the guy is what he appears to be.
Again, it's worth a look, and some thought.
