This writer skipped over one of the major reasons why people have children: a sense of obligation and loyalty to their culture and people. Socialism has convinced europeans that they are atomized individuals whose only loyalty is to the state. As such, they live their lives as if their only loyalty was to themselves and to materialistic consumption.
Healthy "tribal" cultures place a variety of carrots and sticks in front of their members to procreate so as to ensure the survival of the tribe. Without this motivating force, people naturally follow the most convenient and hedonistic path....and live their lives accordingly.
Part of our TV indoctrinated culture is that teenagers need to act out in defiance against their parents in order to reach the next stage of maturity. Sometimes this leads to things being done and said that aren't patched up for decades. And there's no need to do the patching since the parents are taken care of by Soc Sec and the kids are reinventing the wheel as they start their new careers without "meddling" parents.
Rabid individualism without regards to supporting one's "tribe" is a recipe for social collapse.
