Yes, but I don't see even one tenth of the posts joining the peace core, or exclusively clean up the messes of crazy posts just because there are so many of them. You'll need to think of more standard jobs.
Someone with weather control or a green thumb would make a killing in agriculture.
That was exactly my thought. Posts aren't motivated by their power to use it, or at least, most aren't. It might be a compulsion for some, but that's a minority, so most people can go without using their power, and so don't have to get a job that makes use of it. And here's another thought. Someone with control over plants like Poison Ivy or Layla from Sky High, as a marijuana grower/dealer. Can you say SuperPot? Mods, please note, I'm not advocating the use of any illegal narcotics, I'm merely suggesting a logical progression of events in my fictional universe.
