Maybe they could sell fruit, if it was fruit that they didn't like. You could set up some sort of "system" where the customers put money in a big, sealed box and then was handed a fruit by the gang member. I bet most gang members don't like oranges.
Or they could work at the SCIENCE department of a supplement company, developing new supplements by pouring sugar, NITRATES (salt) and other PERFORMANCE ENHANCING compounds into canisters. I think it would turn out well if you gave them a funnel and white lab coats. It would give them a sense of self worth and help developing their character.
This may actually be what the American economy needs right now.
