Bill Gates said the wealthy would be worth a third as much if he designed the tax system, but unlike Sen. Bernie Sanders he wouldn't ban billionaires.

Elsewhere we hear from pop star Lady Gaga, U2 singer Bono, film director James Cameron, Dr. Anthony Fauci, and Sen. Bernie Sanders, who pushes Gates to an uncomfortable silence, at least in the trailer, when he says that Gates is among three people who own more wealth than the bottom half of America.

Phoebe Gates, daughter of Bill and Melinda French Gates, said she has had friendships end because of the vaccine conspiracy theories about her dad.
