Still it can work well for early stage startups and provided that they won't hire those who have children. They don't anyway (it's a discrimination, a big topic, but a different story here).

Quit your job? Move on to the next one, you will have some buffer time.

As a father, I find that kind of brushing off the needs of people with family decidedly distasteful.

As a father of 3 I even wrote an article about ageism in this industry and especially the so called startup culture. Why are you downvoting me?
