Assuming you have a home and don't have to contribute.
I don't have much sympathy for the mindset displayed in this article (I've moved 5 times, ~4k miles total, on near minimum wage salaries), but you are making the same kind of assumptions these kids do.
A lot of people have struggling parents who aren't able to provide a free ride. Some people just have shitty parents.
It's easy to assume there is always a place to call home when you have it. Be glad you do.
You might be holding down a part time job while in college, and using that money to pay for your apartment. In that case, of course, you may be able to wait for your lease to be over - hopefully you timed it to close to your graduation date.
Ah, sure. But in that case it's not a huge deal, you just wait, or you work out a deal with your landlord. Most of the time if you talk to them they'll be ok with working with you to sublet your apartment for the balance of your lease.
This depends hugely on where you live. Good luck trying this approach with an apartment complex in Dallas, TX, for instance. (We did. We failed. We paid.)
(Some more context - I was long past college when this happened, and got a job offer in New York where I live now.)
