Steve Jobs, the child of two Ivy League students? That would in no way qualify under "you shouldn't be having kids if the only job you can get is McDonalds or Yum! Brands".
Jobs's birth parents were 23-year-old grad students at the University of Wisconsin, not a population known for being rolling in dough. They decided they were too young to marry and have kids.
From the page you just linked, Jobs's birth father was "the son of a self-made millionaire".
Who nonetheless didn't feel like his life was secure enough to marry and raise a family right then.
Job's biological father came from a wealthy background. He and Job's mother met at University of Wisconsin (not from the US, but pretty sure that isn't Ivy League). The mother was working as a TA, so she wasn't wealthy.
TAs can't possibly be wealthy? That's news.
OK, I misremembered. University of Wisconsin is not Ivy League. But I stand by the point; working as a TA doesn't make you wealthy, but it does mean you can get a better job than working at McDonald's.
