I'm a millennial (30) and I don't agree with this chick, but the older generation deliberately buries their heads in the sand on the cost of everything today, but especially education, back then. Also nowadays everyone has a college degree.
She should have gotten a roommate or considered a different job. One thing I will say though, San Fran is exceptionally expensive- way more expensive than NYC, and unlike here, there are not cheap areas.
NYC allows a little more hustle. If you're smart, you know where you can pay $900-1000 for rent, maybe even live alone, be right off public transportation, get a lunch for $5-7, get cheap groceries, etc. You can go to RU or a SUNY and not be (totally) destroyed by debt, but eventually if you want to make serious money you will likely need an advanced degree or certification of some kind. These are the kind of things I did. They're not options for everyone though.
This is versus my parents' generation when CUNY was free or close, not everyone had a college degree, and any graduate degree was the equivalent of being set for life, a family could live off one salary in a nice home in a well off suburb, etc. My condo three years ago cost around what my parents paid for a 4 bedroom house in an upper middle class town in the early 90s, neither of them went to college, and my mom didn't work until I was older. Today I can afford a nice life for myself, but if I was to get married and have a kid, my wife would have to work. It's something else that will be lost on the next generation. You can't just blind yourself to these things.
