Why Bill Clinton Makes SOO much for his Speeches

According to Russell Roberts it is not the quality of his speeches or speaking ability:

But it did remind me that Bill doesn't get paid for the quality of his speeches. He earns a great deal of money for two reasons. One is that people want to mingle and listen to celebrities of any kind. An ex-President, no matter how miserable an orator, can make a lot of money selling face time. But the real reason Bill is in demand is his wife. He's the husband of the Senator from New York and possibly the next President of the United States. People are paying for influence and access to power. They're buying a lottery ticket. Just one more reason that campaign finance laws are ridiculous.

There's more.
