I think this is an interesting discussion in a world where raising the minimum wage and "living wage" are somewhat hot political topics. Why is Youtube allowed to have a business model where they can arbitrarily decide not to pay you for content generation? Can you imagine a world in which Uber could just decide not to pay you for deliveries until you meet a certain threshold? And then after they've been paying you for a while, they arbitrarily decide to stop paying you for deliveries.
