There's a lot of people here commenting that significantly lower disposable income isn't really an issue because of social welfare. In general I agree with that claim, but talking specifically about pensions/retirement: how can you be so sure that 20, 30, 40 years down the road you'll get the same deal as retirees are getting today? The way I see it, most advanced democracies have some variation of an intergenerational pension system. These systems were planned in a post-war, high-growth context. A lot of countries are having some kind of trouble with pensions, resorting to increasing minimum retirement age (Portugal, UK, Russia come to mind -- I'm sure there are others) or otherwise trying to find alternative funding for increasingly expensive pensions. Again, I still think the trade is fair (less "personal" income in exchange for more social benefits, healthier and happier society), but I find the certainty people talk about pensions a bit odd.
