Should the rich pay more into Social Security?

In an article on Social Security, featuring the false claim that Bush's plan for privatizing is as a result of growing public concern and not his overhyped "crisis" mentality, there was this:

"Social Security is not in a crisis for many years to come," said economics professor Dr. John Nelson. "The simple solution is to take the lid off people who pay into the program. [Alex Rodriguez] makes over $27 million with the Yankees but he pays the same amount in Social Security taxes as someone who is making in the $80,000s."

I initally thought this wouldn't sell anywhere, but after a chat with a friend of mine, I realized that it could if we set up the right "demons" to lay in the equation. Kenneth Lay would be a good one, or even Martha Stewart. What about Barbara Streisand and Linda Ronstadt for the bogeymen on the right?

Any other suggestions?
