No, parents don't necessarily get all the credit for raising someone. For one thing, not all parents are good at the job of raising children. For another, even if someone has exemplary parents, the fact remains that they still have to absorb and ingrain all the lessons that they're taught. So even in the best possible circumstances, children still get some of the credit for turning out alright, and in most, they get more.
It doesn't matter WHO raises kids. They get support from other till they turn 21. Some get cut off sooner.
All food and clothing, money teaching.....everything they are
is from others who give with little out of love
for family or strangers. The "humanist" taking credit for only himself to credit is a blind ingrate.
