It's all very nice disparaging people for having found a passion, but when I read Masters of Doom, I didn't pity John Carmack and John Romero and their gang for programming all week, then 'borrowing' work computers to program and play D&D all weekend. I admired them. They found a thing they loved to do with people they loved to do it with.
Other people have to do many things to be happy, but they found it all there! These were incredibly intelligent, incredibly creative people expressing their intelligence and creativity. They weren't lesser men for their passion. It elevated them.
You're right, we shouldn't disparage people for working long hours in pursuit of their passion. But we absolutely should disparage investors and founders who seek to exploit this youthful passion and energy to enrich themselves without fair compensation. The tricky part is actually defining what's fair.
