KEY POINTS
  • Hedge-fund manager and Democratic presidential candidate Tom Steyer says fellow billionaire Michael Bloomberg should join him in supporting a wealth tax if he decides to enter the race.
  • Bloomberg's $52.8 billion net worth would make him the wealthiest candidate by far, eclipsing the $1.6 billion net worth of Steyer, currently the richest candidate.
  • Steyer's support for a wealth tax runs contrary to many of his billionaire peers, who have slammed proposals from the Democratic field as being a punitive redistribution of wealth.

Democratic presidential candidate Tom Steyer on Thursday called on fellow billionaire Michael Bloomberg to join him in supporting a wealth tax if Bloomberg enters the race.

"If you're Mike Bloomberg or me, people who have been incredibly lucky and incredibly fortunate, you should be for a wealth tax if you want to have bona fides in terms of addressing inequality," Steyer said on CNBC's "Squawk on the Street."
