> So the theory is someone is going to hire a teenager for less than minimum wage to begin with but then will give them wonderful opportunities later on.
It's a lot like the "theory" that someone fresh out of college becomes more valuable after a couple of years of experience. Or, at the very least, has demonstrated how she is better than the typical college grad.
Is hristov a counter-example to these theories? Has his/her actual or percieved value been completely constant over time, regardless of how s\he's spent that time?
If it has, why is it absurd to think that time spent working might have some effect on one's value as a worker? Or is it that teenagers are different?
