I find it interesting that the IRS can actually reach in to your bank account and take back what they're owed under existing law. If Janet Yellen already knows where all this money is I'm sure the IRS does too. So why haven't they? If they actually had numbers and numbers they would have done it.
What Yellen and Khanna are doing is posturing. They use their status to throw out some BS. You fall for it. And then you demand that people like Khanna go out and raise taxes based on your erroneous belief that this was just about collecting taxes already owed. Whatever loop holes are in the tax code were put their on purpose by members of Congress.
If it were actual tax evasion the IRS would seize the assets under their already very extensive powers. Doubt me? File some bullshit IRS form alleging you deserve a bunch of money back and see what happens for yourself.
