If the experts are right in their calculations, then we face the prospect of millions of people retiring into poverty from the American middle class in the years ahead. That has all kinds of social and economic consequences. We need to anticipate those and start tackling the problem in a constructive way.

In Western Europe, most countries have variations of the lifetime pension system for most workers so they are keeping the system that we are walking away from. By comparison, 50% of the American workforce is not offered any retirement plan by their employers. And of those who are offered a plan, roughly 25% do not choose to join. In other words, everything is voluntary, and that's one of the reasons our results are so perilous for most people.

The issue of the pension gap has got to become visible and important to millions of people before Washington will respond seriously. Right now, everyone thinks it's his or her own problem and that individuals have to do better and save more. Of course, that is true. We all have to save more and take responsibility for our own retirement. But we have a huge social and economic problem on our hands.

I don't know if that's true or just wishful predicting.
