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.

Social Security is the foundation stone of that kind of retirement security. It not only needs to be strengthened in order to make sure it's there for younger baby boomers and Generations X and Y, but it probably needs to be strengthened and expanded because the retirement benefits now being offered by most employers are not sufficient to support middle-income Americans in their long years of retirement.

Only if enough ordinary Americans speak up and demand better from both their employers and their government is the system going to get fixed. But first of all, we have to understand how serious the problem is.

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 personally make sure that some of my investments are in foreign securities or in international commodity portfolios that are independent of the US dollar. But that's a personal preference. I do not invest in currencies because it's so complicated and so risky. I would not attempt that without excellent professional help.

The retirement financial crisis will affect far more people than baby boomers, and certainly it will affect their children. Most of the retirees and near-retirees with whom we talked, said that they were extremely reluctant to have to depend on their children financially, or to think of moving in with their children. But the mere fact that they were discussing those issues indicates that some of them have already figured out that that is what lies ahead for them.

One of the strongest lessons I learned in doing six months of work on retirement topic was how absolutely crucial the Social Security system is for the great mass of Americans. The research of professionals and our own reporting convinced me that many millions of people are not capable of effectively managing the finances for their own retirement.
