It’s an obvious bluff which Ford would be forced to call as their duty to their shareholders.
Alternatively, if it’s not a bluff, then it concedes a level of power over a private company’s business decisions which no supporter of free markets would want any politician to have.
Given that there is a method to deal with this very problem that supports free markets (removal of government economic incentives to export the manufacturing base), Trump here is making an anti-conservative proposal and would move things in the wrong direction. Politicization of the economy is how we got here in the first place.
Yes the share holders, who come from allover the world and do not give a damn about the USA. GloBULLism sucks. Yes, Ford has a duty to its stockholders and the USA has a right to defend herself from gloBULLism thru tariffs and trade barriers.
