I like the OP's idea. Kick out the gulf states. Ten years from now they will have designed a tax friendly republic, most of the "remaining US companies" will flock there, they will thrive and prosper while the cancerous union left collapses in on itself in debt and taxes driven by a socialist agenda. Hell, I'm a New Yorker originally, but I'd sure as hell move to Florida or Texas if that happened. Which is why it won't happen. The government is smart enough to know how it will go. The OP..? Well, he's not so insightful. Let's leave it at that.
Pretty soon if we stay on this socialist course we can open normal relations with cuba as we will be economically indistinguishable from each other.
I'm not so sure. Left to its own devices, I think that part of the country would quite possibly go Third World. Companies might go there for the same reason they would operate in any other Third World country: they'd be able to get away with just about anything for profit. It is the rest of the country that gives those states any credibility they may have on the world stage, and only by association.
Yep, would have the best health care since the "Union" would socialize theirs. The best doctors would come to the new gulf confederacy. Jobs would be plentiful because small business wouldn't be taxed and regulated to death before it has a chance to flourish, and larger corporates would be attracted by reasonable taxation and lack of bureaucratic red tape.
