some minimum wage jobs only give you 15-25 cent raise after your first year. I don't know how its like where you are but around my way that's how it is
And when they increase their value to an employer, I'm certain they will earn much more. In three years, all they're capable of doing is putting on the same five lug nuts, it's going to be a long life for them!
Unless they're on a pit crew for NASCAR.
