Where are they going to go? Honest question, because capital flight is always a threat that never materializes. Turns out the actual pillars of wealth can't easily be extracted out of the country.
Yes and the seeds have already been planted by the current US administration taking various financial stakes in public companies as a condition of corporate welfare.
I don't see this as a good analogy, because the financial crisis bailout appeared to save the companies from shuttering, which is not what happened under the current admin.
Those were just repaying the loans, having a stake in a company is completely different. It's not hard to push that further and in more creative ways too.
Even better, this is a policy that has been done by multiple Presidents. All you need know is an executive willing to do it as it's clearly in the President's power to dictate commerce if they can force the federal government to take equity in various companies at any time (even better if said company relies on US welfare to exist).
Huge difference between taking an equity stake in a failing company and nationalizing a successful company. Either way, those seeds were planted well before this admin, though this admin can be seen to have watered/tended them.
One of those differences being "Hey, we want to buy some shares at market price, will you sell them to us?" vs "We're taking over your company, and if you don't like it, talk to the men with the guns".
