I mean of the choice is between that and crippling debt and a useless degree, he's making the objectively smart move.
The fact that they were able to buy things while living at home just drives the point home even more- he would not have the disposable income to make those purchases for many years if he decides to go to college.
Wut? Are those the only choices? Is there nothing in between? Lay off the drama. I don't feel like my degree was useless (and I'm not even working in the field I got a degree in) and I certainly didn't graduate with crippling debt.
He works as a landscaper in Minnesota, which I presume does not offer robust employment year round. Even if he could work all seasons doing landscaping, his pay would come out to $26,000 a year, assuming he takes no days off.
I am not sure this is a smart move. It seems like he is hoping his music career pans out, but we aren't given a lot of insight into his talent level there.
