We have not.
A tax measure that provides a road map to increased inequality in one of the already-most-unequal industrial democracies and shreds the social safety net woven in the depth of the Depression to prevent a hard turn to fascist or communist revolution, and that is "supported" by, at most, a quarter of the citizens of the affected polity (and that in the midst of a relentless, unashamedly vicious barrage of lies from the ruling party that suggests that at least a portion of that 25% would fall away if they understood how nakedly plutocratic this legislation is) is as close to the definition of "taxation without representation" as I can think of short of a genuine occupation government.
If our political system has devolved to the point where a coterie of neo-Gilded Age fantasists can impose their Sharia Law on three-quarters of the populace, then we have put a wrap on the American Experiment.
In a truly republican nation this would decorate Pennsylvania Avenue with a festive holiday display of heads on pikes.
It has not and will not.
