Foreign high-tech workers are taking American jobs and making Silicon Valley's diversity problem worse, Rev. Jesse Jackson said in a Fortune interview.
"There are Americans who can do that work, and H1B workers are cheaper and undercut wages," Jackson said, referring to the class of visas most often used by tech workers. He said the tech community had a problem letting new people in and giving them opportunities.
Jackson has been campaigning to improve diversity in the technology hub, pushing a number of companies over the last year to publish their hiring statistics.
"We need to put pressure on the system to open up," Jackson told the magazine.
