The entire 'gig economy' model is exploitation. It only works because of income inequality. It requires a large pool of workers who don't make enough money to support themselves (due to insane healthcare and housing costs, and low wages and benefits) and thus will take any money they can get, despite the poor pay, long hours, and lack of benefits. It's taking a person slowly dying of thirst and offering them a thimble of water in exchange for knitting a sock.
