I hired a couple young men - early 20s - to move a whole bunch of wood and to split the larger pieces; hard workers, I was happy to pay them $20 an hour each although technically they charged less.
My stepdaughter and b/f - wanted to do some work for us. I knew they just weren't up to the same level; they just weren't up to 7 hours of hard physical labor a day . I had them clear out a shed - while they did a great job, have to say I didn't pay them quite as much.... still more than minimum wage, though.
So McDonald's doesn't pay some employees "quite as much" if those workers " just weren't up to the same level", just like a liberal.
What's wrong with that?
