I question your assertion because one of the reasons people used to depend on strong families was children were expected to work for the family to survive. Furthermore, children could also be sold into slavery at various points in history.
I think its more like this ... police departments arose because people preferred to pay someone else to do policing and delegated their responsibility. People prefer to pay someone to educate and raise their kids. People prefer to pay into social security than rely on kids for elderly aid.
I think the reason for any problem is much more likely to be found in a mirror than blaming government or elite. Neither government or elite have any inherent power unless given by express or tacit consent.
Let's face it ... human energy (ie. work) is like electricity in that it seems to prefer the least path of resistance.
