A great point, and I often wonder - is it about the diploma at all?
What those 'for-profit universities' tend to instill in our heads is the 'all for-profit' mindset. Do I really want a doctor, a lawyer, a carmaker, or a house builder with the 'all for-profit' mindset?
I got my diploma at 46. Just for the sake of it because everyone wanted to see some diploma. And during that final year of studies, I only wanted to free my schedule and return to research and study 'the hard way' - what I want, when I want, and the way I want. And to build a broader mix of various skills.
