This seems unnecessarily snarky. OP didn't say "all > 30 year olds have these issues", he was talking about his own experience and how it shapes his startup aspirations.
I agree that I was overly snarky, though only slightly. I disagree that Kids & Mortgage is still very common. Maybe just common, and even then, there's often additional nuance (second marriage, renting not mortgage, etc.)
