> With the high cost of college I would argue making mistakes has become much more expensive than it used to be.
I don't know. The biggest cost of college is still, far and away, the time cost. I don't think that is getting any more expensive in the average case. A degree still roughly takes about the same amount of time as it always has. Other associated costs have definitely risen, but are a drop in the bucket compared to the total cost.
From what I hear from my young coworkers they often owe 40k after two years of college. If you realize then that you took the wrong major switching is difficult with that debt load. That is, unless you have a rich dad...
It was once promised that getting a degree would increase your job income by more than that $7,500 (or whatever number fits the situation). But incomes have been stagnant for 40+ years, with no sign of that changing. Without rising incomes, incomes simply aren't rising to compensate for the growing postsecondary educated populace.
