for tens of thousands of years mankind spent 80%+ of the day with their offsprings/families/villagesFor tens of thousands of years kids played with other kids or hanged in the village watched by the older people in the community, while fathers did some guild style job or worked at the fields, and moms cooked and tended the house. They got together to eat and sleep at various points. For less fortunate families, kids started working as early as 8-10 years old. Little kids (even 8-12 years old) were also very frequently made to cater and babysit younger siblings while the parents were working.
>why have kids in the first place if they are then put into daycare until they are grown enough to not to have to care about them anymore at all...
This presupposes what it was supposed to prove, that 1-2 hours per day are not enough time.
It also comes from a place of big privilege, as for a hell of a lot of parents 1-2 hours per day are more than their hand-to-mouth work affords, so the point where it's like questioning why those bad parents of starving children that don't have bread are not feeding them cake!
