Justice it is or it isn't?

This is the world's justice:
Survival of the fittest.
The fitter entities will produce even fitter offspring, until certain point when environment shifts and the fits become unfits.
That's why wealthy families can raise more successful children, due to higher education, and these children can become managers right after grad school, while their fellow poor mates are still climbing the corporate ladder from the very bottom.
That's also why old-time educated families aren't the richest in the present day. These families settle in the middle class, looking disapprovingly to the new-rich, who waste wealth for hedonisms.

Oh, feeling very motivated! How ironic!
