McD 'university' grads make a lot of money as managers and their school is free. Costco is another one of these companies where you can work at lowest level and move to upper mgt so staying there 4 years doesn't always mean burger flipping.
I've seen someone get put through management school for McDonalds and they went from 'order taker' to owning their own franchise in about 10 years. That's ambition.
