Helpful note on taxation from the NYT. We wouldn't want you to pounce on a single word:
"We believe abusive tax schemes, if left unchecked, will erode public confidence in our voluntary tax system," the senators wrote in June. (Voluntary refers to people and companies assessing themselves and filing tax returns subject to audit, as opposed to a mandatory system in which the government sends tax bills.)
It doesn't mean taxes are voluntary. I never would have guessed. Kudos to the NYT for clearing that up.
