Interesting take, and it has evolved so much that we as humans take that attitude even when we don't even have or want kids.
There is a lot of "I can do it but you can't" Here on Hive. It's a childish and hypocrite attitude that is pretty easy to spot if you remove yourself a little and see everyone without idolizing them.
A lot of assumptions without any investigation, and a lot of badmouth fully knowing what you are saying is not true and will have an impact.
And all seems to be pretty much what you describe, a fear of let others succeed. I mean, Hive could be big enough for everyone to succeed if people drop this behavior.
