I’m married with two children, and my spouse effectively[1] doesn’t earn an income. I’d consider running a startup, but my life situation requires that I have a reasonably steady annual income of ~$125k.

That doesn’t mean I have a lower risk tolerance, or at least not exactly. It means I have a higher risk floor that I had fifteen years ago.

[1]: they have a small business that I’d reasonably say is their life’s work. Because of my income they don’t have to make it a steadily profitable business and can therefore reinvest the profit it produces. It’s a business serving children and is parts of the burgeoning local arts community. It’s very helpful to be able to waive fees and offer small scholarships for children in our area, where the median family annual income is <$30k. It’s also been a blessing to be able to hire teenage students from time to time; more than once that’s turned an extracurricular activity that the kid is passionate about from a cost to a small source of income for a family of very limited means./
