Useful and Wasteful Charity?
One of the more depressing implications of careful economic analysis is that it is very difficult to actually give away money in ways that actually benefit the people toward whom we are trying to be charitable. The law of supply is pretty robust here: if we effectively pay people to do something (stand in line for a handout), we will get more of that something (more people standing in line for a handout). You see it every Thanksgiving and Christmas: people lined up for blocks waiting for $0 food, clothing, shelter, toys, etc.
