They all think it's beneath them and think that at 19-21, they should be on $50k a year.
They all is an overstatement.
The place I worked at as a 19 year old treated its staff rather well. As a result myself, along with the others in that age bracket, were happy to work 50+ hours a week and our efforts were rewarded with a pay over 50k. Occasionally someone would come along that matches your description and they wouldn't last very long.
