Yeah, the people "getting away with it" in this case aren't those paying withholding or even mostly individuals... they're corporations bilking the government and every other taxpayer. It's more like cutting back on the FBI when there's an outbreak of organized crime...
The problem is Congress, not the IRS. Most corporations pay the amount of tax they owe under the law, but the law is written to allow tax evasion. The IRS can’t do anything about this. The fix is to close several well known loopholes.
That is not tax evasion. If the law is used to avoid paying a tax it is legal. Tax evasion is when you don't pay taxes that you should have paid and somebody often goes to jail and/or pays penalties for it.
