Since they are not employees, they don't get a wage, so minimum wage laws don't apply.
> Case in point, when Uber/Lyft was forced to pay their drivers a minimum wage that accounted for expenses, Uber and Lyft stopped accepting new drivers in New York City. They were force to act according to true supply and demand.
This was the result of the city of New York deciding, on behalf of the taxi lobby, that there were too many Ubers on the street, so they fixed the supply to make the average pay add up to 17$/hour (which is not a minimum wage either).
Real supply of drivers was higher than that, people that wanted to drive at lower price were effectively prohibited from entering the market.
