No, it isn’t.

From October 7th:

Vice President Joe Biden is combining his traditional gaffe-making with some tentative criticism of President Barack Obama’s economy, as he embarks on his effort to win the Democrats’ 2016 nomination.

“In a macroeconomic sense, the economy is roaring, everything is growing great [but] the truth of the matter is, a lot of folks are hurting. A lot of middle class folks are in a stagnant position,” he told a meeting of Democrats in Los Angeles, Calif.

HIs gaffe wasn’t a diplomatic error or a accidental insult, but more of a fake humble-brag.

“My [Senate] colleagues would tell you, I’m referred to in Washington and nationally as ‘Middle Class Joe,’” he told the Democrats, who included the Italian-American mayor of L.A., Gil Garcetti.
