From today's Wall Street Journal Editorial:

The former, and perhaps future, first couple earned $109 million over the past eight years, putting them among the top .01% of taxpayers. Apparently the Bush years haven't been a Depression era for everyone. The bulk of the Clintons' income came from speech-making ($51.9 million) and book-writing ($29.6 million), and it's hard to begrudge their desire to cash in on the Presidency after toiling for so many years in public service. The Clintons are hardly unique in showing that in today's Washington you can do very, very well after you've done good.We can also now understand why the couple took so long to release their returns, and are still reluctant to release other information. Their political status has given them access to wealthy folks who've helped make them rich. For example, Mr. Clinton raked in as much as $15 million working as an adviser and rainmaker for billionaire financier Ron Burkle's Yucaipa firm. We're not sure what advice Mr. Clinton gave but it must have been fabulous. The former President also took in $3.3 million in consulting fees from InfoUSA CEO Vinod Gupta, who has also helped fund Mrs. Clinton's White House bid. These are not opportunities that fall into every American's lap.
