Not sure I understand... Can you elaborate?
Law proposal: After a company makes over a 500 million USD in revenue 2 years in a row, the citizens of the country it operates in automatically become the company's shareholders and board members. There could be a more nuanced version of this that gives the public only some percentage - say 50% - of voting power and company's profit so that there is still strong incentive for the existing shareholders to stick around
Genuinely curious - what do you think is most likely to go wrong? I imagine there would be quite a lot of corporate pushback via lobbying... is that what you mean?
