Breaking up big tech was a big topic of discussion at the most recent Democratic debate - here's where all the candidates stand

Warren supports increased regulation of tech companies. She describes them as monopolies, and she says that her administration would pass legislation designating them as "platform utilities," which would prohibit companies from owning both a platform and participants, like Amazon acting as a seller in its online marketplace, for example. She would also appoint regulators dedicated to undoing anti-competitive tech mergers.

Warren also recently pledged not to accept large donations from tech executives.

CEO Mark Zuckerberg said that a Warren presidency would "suck" for Facebook in leaked audio published by The Verge.

Sanders didn't get to answer the question about tech monopolies at Tuesday's debate, but he did announce a plan for corporate America that would mandate all large companies be partially owned by workers, which would apply to big tech companies.

He told The New York Times, "public policy is so far behind the explosion of technology, that it is really one of the weaknesses of where we are right now as a country."

Sanders has also made wealth inequality a signature issue of his career, and he recently tweeted "billionaires should not exist," which would include tech executives like Mark Zuckerberg and Jeff Bezos. In fact, Mark Zuckerberg even said that he agreed.

Yang does believe that some tech companies should be broken up, but he also said he believes the issue is more complicated than how Warren and Sanders portray it. In May, he suggested that Silicon Valley companies should break themselves up.

Some outlets have called Yang "Silicon's Valley's candidate" for his apparent nuance and understanding of how the industry works.

He also believes in regulating AI, and he has positioned his support for universal basic income as the answer to increasing automation.
