"Forbes 400" list reveals America's wealthiest

Forbes Magazine unveiled its 34th annual "Forbes 400" list, ranking America's billionaires who have a combined net worth of $2.34 trillion.

This year the list had a requirement of a record $1.7 billion, and 145 American billionaires did not make the cut.

Revealed first on "CBS This Morning," here are the top five wealthiest:

Although he stepped down as chairman of Microsoft last year, Gates took the number one spot for the 22nd consecutive year. Gates is now focusing on humanitarian work with the Bill & Melinda Gates Foundation.

But it wasn't any of the wealthiest five who made the cover of Forbes Magazine. With Donald Trump constantly in the limelight, Luisa Kroll, the magazine's assistant managing editor of wealth, said they "couldn't resist" giving him the honorary spot.

Still, Kroll noted that the GOP candidate is actually worth less than what he claims--a net worth of $4.5 billion compared to his claim of over $10 billion.

This year's "Forbes 400" list also confirms that America's rich continue to get richer. Most on the list--more than 200--jumped in net worth.

Gains were especially visible among the startup tech sector, debuting new faces such Evan Spiegel, the CEO of Snapchat, who is also the youngest to make the list at just 25 years old.
