I mean it rly depends on what you wanna do, and what your definition of success is. I actually need a Master's degree or higher to be successful in my field. So student loans here I am! But success for me is also not about money either..
Getting a degree before knowing where you wanna work/what you plan to use it for is ultimately not a good move, true. To me, success means recognition in my field, protecting our resources & being comfortable/sustainable. So I be down for student loans for it.
