The agreement as it stands would have no impact here in the U.S. The minimum corporate tax rate they set is 15%. The U.S. currently has a flat corporate tax rate of 21% which is the lowest it’s been in decades (at least) and isn’t going to be getting cut any time soon.
Yes, it might actually be a win, except for the fact that a global tax has to include subsidies, which it won’t. I also am highly skeptical about any kind of global tax.
