Teachers should not be paying full price at Harvard (I don't know if Havard even offers a teaching degree), there is value in a teaching degree but only enough for the much cheaper state schools.

I have no problem with people wanting to be artists. The world needs art. However I have a problem with someone spending more than they can afford on anything. Want an art degree, first get a job and save up as art will never pay the bills (there are exceptions that prove this rule). Once you can afford to live (that is eat and a tiny home: the minimums) go ahead and get whatever luxury you can afford. Some get an art degree, some a nice car, some collect stamps, you can have a family. I don't care much what you choose so long as you are not beyond your means.

To put it a different way, if you are making an investment then it needs to be a good investment with a return on investment. If you are not making an investment that is fine but then you need to be careful not to destroy your future on bad choices.
