Welfare societies like Greece borrow from the future; trouble is, some of them don't have one

What's happening in the developed world today isn't so very hard to understand: The 20th century Bismarckian welfare state has run out of people to stick it to. In America, the feckless insatiable boobs in Washington, Sacramento, Albany and elsewhere are screwing over our kids and grandkids. In Europe, they've reached the next stage in social democratic evolution: There are no kids or grandkids to screw over. The United States has a fertility rate of around 2.1, or just over two kids per couple. Greece has a fertility rate of about 1.3: 10 grandparents have six kids have four grandkids - i.e., the family tree is upside down. Demographers call 1.3 "lowest-low" fertility - the point from which no society has ever recovered. And compared to Spain and Italy, Greece has the least worst fertility rate in Mediterranean Europe.

So you can't borrow against the future because, in the most basic sense, you don't have one. Greeks in the public sector retire at 58, which sounds great. But, when 10 grandparents have four grandchildren, who pays for you to spend the last third of your adult life loafing around?

By the way, you don't have to go to Greece to experience Greek-style retirement: The Athenian "public service" of California has been metaphorically face-down in the ouzo for a generation. Still, America as a whole is not yet Greece. A couple of years ago, when I wrote my book "America Alone," I put the Social Security debate in a bit of perspective: On 2005 figures, projected public pensions liabilities were expected to rise by 2040 to about 6.8 percent of GDP. In Greece, the figure was 25 percent. In other words, head for the hills, Armageddon, outta here, The End. Since then, the situation has worsened in both countries. And really the comparison is academic: Whereas America still has a choice, Greece isn't going to have a 2040 - not without a massive shot of Reality Juice.
