| Many people -- especially the
baby-boomers born between 1946 and 1964, who will be retiring over the next 20
years or so -- will be asking themselves whether they will have enough to keep
them comfortable in their old age, even if they save a lot. After all, it is
generally accepted that they cannot rely on the state. The burden on the
taxpayer would be too great. But, as already noted, financial wealth is just a claim on the assets produced by the economy. Making pensions a claim on the private sector rather than the public purse does not change the problem.
