What a difference a few years — and a job in the White House — makes.

Back in 2007, then-Sen. Joe Biden lamented his relative lack of wealth, saying during a debate that his “net worth is $75,000-$150,000. That’s what happens when you get elected at 29.”

He cracked the joke at Barack Obama’s expense, and he portrayed himself as so poor, he opposed the notion of working in Congress or the White House for a minimum wage salary.

“If I could get a second job, I’d do it,” he said.

But now, it turns out, the Bidens have hit the jackpot since being out of the White House for 2 1/2 years.

CBS News reports:

According to financial disclosures and tax returns provided by the campaign, former Vice President Joe Biden and his wife Dr. Jill Biden have earned more than $15 million since 2016.

The majority of the income comes from book deals and speaking engagements, with the Bidens earning around $9.5 million in 2017, the year after Biden left office. That year, the Bidens donated more than a million dollars to charity, according to the documents.

Since leaving office, both Bidens have worked as college professors. Jill Biden taught at Northern Virginia Community College and made more than $180,000 in two years, while her husband was named the “Benjamin Franklin presidential practice professor” at the University of Pennsylvania, earning more than $775,000 in two years.

The Obamas have done quite well, too.

Business Insider reports their net worth is anywhere from an estimated $40 million to $135 million.
