Because the idea is that the government is corrupt and useless, so the old man who chooses the "special" people he entrusts money to chooses them because he feels they have the ability to change the country.
It's weird some of the people he chooses, and a lot of them just use the money for personal things (which they can get in trouble for), but some of them do make a difference. I really, really liked this anime. You should definitely check it out! It's so different from any other series I've seen, which is why it stands out to me.
