Much of that regret comes from cost pressures, not the actual existence of the children.
Well, yeah, it’s not saying that people hate their kids. LOL
According to the same survey the article linked to, people are less happy when they have more kids (than ideal) vs having fewer kids (than ideal). It doesn’t say that cost pressures are a main factor.
If you look at the reasons why people don’t want kids (original survey linked in the article), then you could assume that those same factors explain why people having regrets. No opportunity to grow as a person, the time commitment, less freedom, the derailment of their career, etc. (per the survey results).
A different study said that:
" Older parents with minor children still at home are less happy than their empty nest contemporaries by about 5 or 6 percentage points. And … Both men and women report less personal happiness and less happy marriages when there are minor children around the house."
But I suppose happiness and regret can be different for each person. Having a child grow up to be a successful, contributing member of society would probably make parents happy.
I’d say that the vast majority of parents aren’t in that situation, though. They not only have to continue to support their child into adulthood, but they never had a chance to develop personally because their child was never independent enough. I can see how that would cause a lot of regret for older parents.
