The principle was no taxation without representation. We have representation.
Have you ever tried even getting in contact with a single US Senator to make your voice heard? We are paying literally hundreds if not thousands of times more of our income to the government than the colonies EVER did. And we have about the same amount of power over the legislature that they did. I'd say we are NOT represented at all now - we are overtaxed at a burden that would have caused a second Revolution if the founding fathers were living today.
