We all participate in society, work in society, build society, rest in society, and benefit from society. People who paid their dues doing these things receive retirement at old age because of society. You can find edge cases where society isn't perfect, but none of these edge cases will justify the sweeping claims you made. You threw the baby out with the bathwater big time. You're pretty much advocating for anarchy and chaos.
Economic systems and religious systems exist because they are useful abstractions. Sometimes they map onto physical reality and correctly measure and explain the movement of commodities and as a result we get a more connected world and more trade. When the abstractions don't serve us well anymore, they get upgraded to address new complexity. That is why we have economic theory. Sometimes these abstractions map onto human emotions and lived experience across the spectrum of ages to give people hope and to answer the questions science cannot. That is why we have religions.
They're all beautiful, they're all abstractions that are useful, and they exist because everyone wants them to. There is no conspiracy by the old to subsume the young.
