Re: One problem with these models
In my humble opinion, the only -acceptable- way out of this conundrum would be shorter work hours for everybody, mandated by the State
French tried it by switching to 4 day work week. They tried it too early. While their per-hour productivity is quite high (used to be significantly higher than UK), it was not high enough to sustain it and then the financial crisis hit them for 6. So they are now rowing back on this one.
That is one option, however, while there is quite a bit of runway in it, it is also limited ultimately leading to the obvious situation where we will have no choice, but to have "Third" as a swear word. That as well as licensing parents and giving child permits.
