I think OP has a point. MZ was comfortable enough leaving school for a semester, and that too after being put on academic probation for violating serious codes of ethics. Despite all that, he still managed a $500k seed investment from Peter Thiel. Students who grow up in poverty and put the work in to get into college, let alone a prestigious one like Harvard, are usually fighting to do everything right just to make it through, and many don't because they can't make financial commitments (and yes, despite tons of scholarship money) or personal commitments with family. People like Mark always had the security of their family's relative wealth and security on top of their general status in society. That's not a luxury afforded to most, and certainly not those from low-income backgrounds.
