We definitely work too much in the US. I’m guilty of it and my kids call me on it regularly, though they appreciate that I make time for them. In the professional world, even if you’re an elite worker with skills that would be hard, and expensive, to replace, it feels like you’re in a race to justify your income and leisure time. I think we have an out of balance work ethic here, but I don’t know how to fix it.
Single mothers and the less common single fathers have even more pressure on them. It’s very hard for a responsible parent to take a break without feeling like they’re neglecting their child. The social structure here, at least among fully assimilated Americans, is wholly inadequate to support healthy family life. Only the Southeast Asians I know maintain the family structure necessary to raise children successfully without killing themselves from the effort.
