Switzerland voted on a 12x initiative a few years ago: https://www.businessinsider.com/switzerlands-112-initiative-why-executives-are-worried-2013-11

Unfortunately it got rejected after big companies threatened to fire their employees and leave Switzerland if this was accepted, that this would destroy the economy, and so on...

Others disagree. According to World Radio Switzerland, Novartis, Nestle, Bobst, and SBB sent thousands of employees letters asking them to vote no to the 1:12 initiative, arguing that it would make Switzerland a less desirable place to do business. Earlier this year the CEO of commodities giant GlencoreXstrata said the company would consider leaving Switzerland if the law passed. “I can’t believe that Switzerland would cause such great harm to its economy,” Ivan Glasenberg said in an interview with the SonntagsZeitung. “And I say that not just as the head of a company, but as a Swiss citizen.”
