Yes, good point, Bonsoir.
And that would be a good thing.
I was just thinking of the German system. They have subsidised childcare for all children from 3yo, and in many states it is free for lower income families. It is means tested, so the more you earn the more you pay.
Those with decent wage pay more (but still a reasonable price, we used to pay ?300 for fulltime day care) and those on low incomes pay less.
It means that women who want to go to work can, and the children from deprived areas, who may not be getting the mental stimulation at home, have some "early education".
Not learning to read or write, but being read to, having a decent meal once a day, being warm.
