Many things are too hard

“perhaps fewer parents would be regretful if our society didn’t make parenting so hard”

It’s too hard. Many of us suffer as a result (though there’s social pressure against mentioning — or even acknowledging — such).

So the article linked above is enlightened to examine it. But when it comes to “what might we do about it,” you can observe that the solutions are, typical of our society’s domain-of-consideration, notably hyper-individualistic: “Decreasing parental regret could be possible with a host of structural shifts: access to reproductive choice, individualized treatment for parental burnout, changes to policies regarding child care, family leave, work schedules, and the gender pay and promotion gaps.”

The most effective solution would be communitarian: Cohousing. The main problem needing to be addressed is the burden resulting from the isolated-nuclear-family context of modern life. People used to raise children within the entirely different context of extended family and village interdependence.

The isolated-nuclear-family context makes all of adult life too hard. It detrimentally affects the spousal relationship, household maintenance, cultural participation, etc.

Additionally, consider: If a person opted not to have children they still might find some interest and satisfaction in playing an informal “aunt” or “uncle” role if they lived in a cohousing community that encouraged shared, village-oriented, childcare practices.

Personally, I think it would be advisable to decrease the human population on the planet. It would easier to advocate for just-one (or none-at-all) families if opportunities for joint shared child-rearing were readily available.
