There's about a million people making at or below minimum wage in the US. Not nobody. That isn't counting situations like Uber and Amazon contractors whose expenses like gas and wear&tear aren't appropriately accounted for. But it is true that a smaller percentage of people are at the federal minimum wage, thanks in part to individual states with higher minima.

A majority of states set a higher minimum wage than the federal limit, and unless I missed something the only highly populated state without a higher minimum is Texas.
