> If work is everything, shouldn't we set aside some time to raise the next generation of workers?

I don't think work per se is everything. But working on world-changing things is.

At least concerning the situation in Germany, where there is compulsary school with a compulsary curriculum (vulgo: 18-19 years of brainwashing), I am working a lot time in the evening on an alternative curriculum (currently focusing on computer science topics since this is something I am hopefully knowledgable about) that enables people to deprogram themselves from this kind of brainwashing to enable them to develop their intellectual potential so that they can begin to work on world-changing things. A lot of highly gifted people already asked me multiple times when they can finally read the first text of my planned series (they are really eager for it) - unluckily there is still so much to do even on the first text.

So the first thing that we should solve is to prepare a curriculum that does not completely brainwash our children. Only when this problem is solved, we can begin to think about how we can set aside some time for them.
