1.1% of workers earn federal minimum wage or less, roughly 900,000 people.
And only idiots think that removing the minimum wage will make things better, but they are idiots, so there's no helping them.
If you eliminated the federal minimum wage then many states would immediately remove it without a replacement and let their people starve to death in the gutters fighting with each other to get any income so that they didn't starve to death in the gutters while raking in the votes from the middle class business owners who are raking in the dough because they don't have to pay their employees any more.
If anything, we need to make the federal minimum wage not be a set minimum but instead it should change and vary based on the economic health of the city, state, and county that the worker works in, and it should be enough that any person who works a full time job earns enough money to afford 1/2 of a 2 bedroom apartment's average rent + food, insurance, car, gas, and fun.
That would give incentive to local businesses to keep their prices affordable because lower prices would mean lower wage costs and therefore more potential profit.
