Are you a company with an American presence? Bam! Show all your paperwork for all your business in all countries and then we'll figure out your tax rate from there.

The problem is, other countries don't require this. Thus, the Republicans point to how unfair you're being and point out that you're driving jobs abroad. And they have a point.

One shitty thing about the Panama/Paradise papers: due to the way taxes in the United States are subject to state as well as federal control, Nevada, Delaware and other states end up being every bit as adequate as tax havens as Bermuda or the Azores. There weren't that many American citizens implicated in either dump because there didn't have to be. Now - so long as the banking industry controls Nevada and Delaware legislatures, don't expect much in the way of change.

That said, the Obama administration's taxation and revenue department grew some real teeth. it's the most successful funds repatriation organization in the world. Piketty singled them out at great length and pointed out that if every country did what the US is doing, it would increase taxable revenues by something like 3 trillion dollars. With just the US alone that number was something unreal like 1.4 trillion.

Now if only we hadn't spent $5.6 trillion on war.
