Seeing that the top earners in America pay a huge majority of the federal income taxes while the lower 50% pay next to nothing..... this proposal is just the latest version of the mob wanting to guillotine the wealthy. If the federal government moves ahead with this type of socialist proposal to "soak the rich" the end result will be the same as what happened recently in France -- the rich will just move out of the country (or move their money out of the country).
As republicans continue to defend the rich as average Americans get poorer more will become democrats. Dems have won the popular vote in 6 of the last seven presidential elections now they closing in on The EC.Red states like Texas,Arizona,Georgia etc will soon be blue.
So now you want to eliminate all International business. We will keep in mind it is the left that wants to destroy both the world economy and the United States. Why don't you simply require the wealthy to leave all of their money before they are hauled away to the camps for "re-education".
For us regular folks the IRS will continue to tax you for 10 years after you leave the country. http://money.com/money/4298634/expat-expatriate-taxes-us-myths/
The true wealthy just move all their wealth offshore and have expensive tax lawyers take very good care of avoiding all U.S. taxes once they leave the U.S. Take a look at what happened in the U.S. when the tax rates were very high for the wealthy previously -- the same thing will simply occur again.
