> I'm really sick of this "the businesses will leave" propaganda.

I don't think anything you've said convinces me it's propaganda.

Businesses are profit-seeking ventures. They will optimize their operations to maximize profits.

So I'm not sure why you'd call it "propaganda" to say that companies will leave. I think the evidence is that they will.

Of course, taxes are not the only variable in a profit-maximizing formula. US companies aren't going to flee in mass if Somalia decides to have zero corporate taxes. But you can't ignore that companies will optimize their operations and structure if they can lower taxes.

The US have something similar just for citizens and greencard holders

So should greencard holders flee the US before they become too rich
