I tend to agree, based on what I personally see. I wonder if part of the reason why is that they are entering a world in full crisis, and service toward others becomes an essential survival skill when dealing with crisis.
There's something Biblical about elders helping lift up the youth and dysfunctional about them continuing to compete as they are today. I can't speak for prior times, but it seems like for at least a generation or two each generation got more wealthy and invented the concept of retirement.
Karma doesn't always hit right away. The older generations who didn't lift up their kids will hit old age and be taken care of by someone--their poor/rightfully resentful kids or help hired with their kids' would-be inheritance.
There seems to be an assumption that the government is there to help and programs are in place, ready to save anyone who wants to be saved at the snap of a finger. As a person who's 5 years homeless (working, college educated) the only real help I get is from employers giving me opportunities to work for above minimum wage at times and customers who tip generously for good service.
There is a facet of service to others in a cash flow based religion, oddly enough. Allegedly even horses feel good after a day of hard work for a kind boss/keeper.
