With a combined worth of $30 million, Chelsea Clinton and her husband Marc Mezvinsky are

on an equal footing. However, Mezvinsky's main source of income is from the finance world.

Mezvinsky got his start at Goldman Sachs as an investment banker. He worked there for five years before moving to 3G Capital, where he oversaw a global macro strategy hedge fund.

In 2011, along with former colleagues, Mezvinsky opened a private hedge fund. Unfortunately, it eventually closed in 2016 after incurring a big loss due to betting big on Greece.

Three years later, Mezvinsky joined private equity firm TPG to work as a managing director and business-unit partner for one of its newest funds.
