However, the problem (at least the US) is first addressed by ending all taxpayer funded public pensions -- all government workers (like almost everybody else today) should be expected to fund their own retirement accounts/401k accounts (actually pensions are a dinosaur). It's way past time to take government workers off the welfare public trough. Pay them an honest and fair wage and treat them like everyone else--today they are treated better than everyone else--taxpayer funded pensions, higher salaries and wages and benefits than workers in the private sector, etc.
