Max S. suggests "more sex with immigrants" as one way to solve the US Social Security system's demographic problem. This seems a good idea (as is sex in general), but it's got to be without the use of birth control. Getting beyond such frivolity, the point which I should have made clearer was that there has to be some sort of link between contributions to SS or pension funds or private savings and increasing labor productivity (defined in an environmentally-friendly way). That link isn't automatic, even with (or especially with) private saving. >> it's hard to see the green agenda holding up before the gale forces of social insurance/tax politics.<< if it doesn't (and it sure looks as if environmentalism is collapsing), we're going to be in even bigger environmental trouble than we are now. in pen-l solidarity, Jim Devine [EMAIL PROTECTED] <[EMAIL PROTECTED]> Econ.
