If I wanted to help clean up local communities, I could make an app that allows you to post trash bounties on your neighborhood, to be collected by people that accept the bounty and go clean it up.
Soon: "CleanCommunities is an evil company! They maximally exploit professional trash bounty hunters with below minimum wage and no benefits, no protective equipment, etc!!!"
Like, geez, I wasn't trying to exploit people, I just saw a litter problem in my community and tried to fix it... I didn't even intend for people to turn this into a full time job, more like a "volunteer service with benefits" type deal...
