Chris Hughes

Facebook co-founder Chris Hughes is an active supporter of UBI, telling NPR in September that the system could go a long way toward rebuilding Americans' faith in an economy many people see as "broken in many ways."

"Rather than try to restructure our economy so it looks like the 1950s, I think we have to be honest with ourselves," he said.

Since jobs are already disappearing, Hughes urges people to consider what systems we'll need to create if millions more follow.
