I would agree if it weren’t almost
everything that must be sacrificed in some capacity. Sacrifice of some things are unavoidable, but when no aspect of life remains untouched it’s too much.
It’s worth noting that such a degree of sacrifice wasn’t always associated with raising children. It used to be much more hands-off and less financially burdensome — responsibilities were split between grandparents, other relatives, and the town/neighborhood, and after the youngest years kids could (and were expected to) spend their time outside unsupervised doing kid things. This gave parents much needed breathing room that no longer exists, thanks to the ongoing stranger danger panic that was kicked off in the 90s, people needing to move around to have a shot at getting a decent job, systematic destruction of safe third places for kids and teens, and pressure to control and structure every moment of each child’s life.
So I don’t agree that it’s individualism, but rather a natural response to financial and societal forces pushing ever more of the burden onto the parents’ shoulders. We’ve created a world that is actively hostile to children and asking parents to just eat the resulting vastly increased costs.
