You write:
"nobody lays on their deathbed wishing they would have spent _less_ time with their family"
I keep seeing this idea repeated time after time, yet I've never seen any formal study of this issue. I know this idea has been asserted by some people with very large followings. Stephen Covey, in his book "The 7 Habits Of Highly Effective People" asserts nearly the identical sentiment that you've expressed here.
All I can say is, from what I've seen, this is just one of those things that varies a great deal from one family to another, and from one person to another. I know that both my mother and my father keenly felt the strain of having children, and both of them wished they'd had more time and money to advance their careers. My dad was lucky enough to be successful as a commercial photographer, but increasingly after he turned 50 he wondered why he never broke through to the top ranks of photography. He made good money but he never became famous. He thought, not unreasonably, that if he had less demands from his family, then he might have more money and energy to reach the top ranks of his field. When he was in his 70s he made several attempts to get into the top galleries in New York City, but he only had one small success in that regard. He died of cancer at the age of 79. Since I stayed with him every day during the last month of his life, I can tell you without a doubt that when he was on his deathbed he did wish that he had had more time for his career - a tradeoff that could only have been purchased by him spending less time with his family.
From what I can see, my dad is hardly an isolated case. When I talk to my friends, and to people older than myself, what I hear, again and again, is disappointment. Many people, perhaps most people, feel that they have somehow failed to live up to their true potential. At least among my friends, most feel that having kids has imposed a heavy sacrifice on them. I can not think of a single one of my friends who hasn't thought, at some point, that they might be much more successful if they did not have kids.
More than that, not everyone is happy with their family life. If you suggest that family life is always rewarding, in a country where 45% of all marriages end in divorce (I'm using the USA as an example here) then you are simply in denial of reality.
I think this is an issue that at least deserves a frank, honest discussion, especially on a forum like Hacker News, where we all expect honesty regarding the tradeoffs of the entrepreneurial life. This is not the right place for sentimental nonsense about the joyous wonders of family. This is a place for bluntness and honesty.
Your attitude about "buy enough downvotes to make this comment disappear forever" is really worrisome.
