New York Mayor and 2020 Democratic presidential candidate Bill de Blasio says American workers need to be protected from automation.

In an opinion article published last week on Wired, he said as president he would issue a robot tax for corporations displacing humans and would create a federal agency to oversee automation.

"The scale of automation in our economy is increasing far faster than most people realize, and its impact on working people in America and across the world, unless corralled, will be devastating," de Blasio wrote.

De Blasio would call the new regulator the Federal Automation and Worker Protection Agency, which would safeguard jobs and communities.

In addition, his proposed "robot tax" would be imposed on large companies that eliminate jobs as they become more automated.

The tax would be equal to five years of payroll taxes for each employee eliminated, according to De Blasio.
