My experiences are limited but consistent. If you can provide even more evidence pointing consistently the opposite direction, I'd not only be convinced, but I'd be thankful. However, I don't think that's easy to do.
The problem with the "evidence" you're using is that it can be interpreted many ways. It's merely a correlation.
In circumstances closer to controlled experiments where I actually gave someone money, they usually wound up worse off in a couple months, not better, unless I made sure the money went towards fixing a real problem.
