What do you think it is?
Having all the responsibility fall on two mostly unsupervised, inexperienced people is fragile and "traditional" gender roles do not alleviate this.
I would also argue, why does the community automatically bear the responsibility for a decision made by two?
With all due respect, Given that you’re on the path to population control and all that’s implied with that, I find it difficult in myself to take what you say seriously.
<< "traditional" gender roles do not alleviate this.
I would personally argue that the "traditional roles" seem to help the offspring on several levels, but I didn't see many studies ( as opposed to non-traditional that is ) to that effect.
