On Monday, convicted con man Bernie Madoff was sentenced to 150 years in jail, and today federal authorities took possession of his $7 million Manhattan penthouse, forcing his wife to leave and look for somewhere else to live.

Ruth Madoff was told ahead of time that she would be forced to vacate her lush Manhattan penthouse, and reportedly she did leave the property this afternoon around 1 PM EST. The penthouse, on East 64th Street will be sold, with the proceeds being used to help reimburse the victims of the nations largest ever Ponzi scheme.

While Madoff's victims are out billions, his wife Ruth Madoff will get to keep a nice chunk of his unjust winnings.

The Wall Street Journal (subscription required) reports that "Ruth Madoff, the wife of one of the most reviled swindlers in history, has agreed to give up her potential claim to more than $80 million worth of assets, keeping just $2.5 million in cash in an agreement reached with federal prosecutors."

Financial journalist Gary Weiss is having none of it:

"One day, I caught him scouting the escort pages that run alongside pictures of scantily clad women in the back of a magazine," she said. "He straightened up in his chair, startled, and said, 'I'm just looking!' " The most interesting bit is this one:

The newspapers are looking ahead to this Tuesday's G-20 summit in London. Since the leaders who show up there represent countries that control 80% of the world's economy, it could be an important meeting. If you live in the U.K. or U.S., your leaders will be attacked by those in other countries who believe that they should not be asked to bail out the errors of Anglo-American capitalism. Beyond that, little of substance is likely to be accomplished.

However, in an alternative universe, the G-20 meeting might actually accomplish something. Specifically, it could get agreement on six principles on which to rebuild American capitalism. Here's what I think those would be:

• Grow through technology-based innovation. The United States used to be admired around the world for its ability to create new industries. In the 1990s, an Asian government wanted to emulate our success and asked me to discuss how the United States turns innovation into economic growth. Unfortunately, since 2000 our ability to take brilliant ideas from our top universities and turn them into venture-backed companies that sell their shares to the public to fuel the creation of new industries has largely been broken. If there is to be growth, it should come from reviving this process.

Since it peaked in October 2007, the Dow has lost 50% of its value. I read an interesting set of expert predictions about when this agony, the recession, will end -- they mostly admit they don't know. So the question they answered struck me as besides the point. A more important question is what to do about it. And since I am not a financial advisor, don't take what follows as financial advice -- it's just my opinion.
