As others have said, some people like to spend 20-30 hours/week training for an Ironmmn, others spend much more than that in front of the TV watching Netflix.
How's that different from working 80 hours/week IF you enjoy it? Just don't force others to do the same.
I'm from South America, have a b.s. in computer science and worked in management consulting before going to business school. For the past few years, I've been working in tech and living with my family in the Bay area solely because of my MBA.
I'm not referring to the academic knowledge I gained, or the global mindset I now have, nor the network I built, which are all valuable. For internationals like myself, the MBA is a great opportunity to make a radical change in your career, as well as your personal life.
Past years:

Next year it could be worse, like the 1st day the cap might be reached. It only shows how important and urgent is to fix the legal immigration system in this country.
