All I get is that people don't spent it on booze (yea trust ppl, not all are addicts) , have more money for food and clothing (o really..) and that the one guy is doing a computer class.
As said, I think it's just a bad video, the actual results might be great. Comparing it to using that money trying to help homeless people in other ways would be even more interesting (finding out if this the best way to invest in to minimizing homelessnes).
