Terry,
The concept of improving conditions and opportunities for family members was not the dominant aim for the hundreds of thousands of years of history.
There was no concept of the "good life". There was only "life".
It was about basic survival. Men beat their rivals to death to protect their offspring. And when their offspring grew up to challenge them they would beat them to death if they infringed on their territory.
The mere idea of "wanting things for your offspring you never had" is a thuggish agenda because they would have to take things from the weak.
What things would a hunter gatherer want for their kids that they never had?
Lifespan was about 30 years for most of human history.
The aim was to simply stay alive. A brutish father that had to physically struggle for his position in the extended family hierarchy would probably consider his
own children as competitors.
We enjoy a great life in the US because we are members of a very successful collective that has dominated all the others.
The reason cults emerge is because people who survived these last million years evolved in a milieu of graybacks and their coalitions.
Sociability is a blessing and a curse.
