No, what happens is the corporations do pass the cost on to the consumers. The consumers want to buy the least expensive products, which turns out to be a product from china. You see, when you raise taxes on American companies you actually end up subsidizing imports. It's a vicious cycle and a large part of why most manufacturing has moved out of America. America has one of the highest corporate tax rate in the world now, research it for your self.Okay... by your logic we should get rid of corporate taxes so they can pass the savings onto us! Do you trust them to do that? I don't... I doubt many do.
Besides, although your statement is true to an extent, once you consider the downward pricing pressure built into capitalism - you'd realize that's largely prevented. If your competitor is willing to suck up the cost of their income taxes and earn a lower profit to out price and outsell you, you'll need to do the same thing to survive. Most of the things we commonly buy are from very competitive markets(think foods like wheat, rice... commodities like gas) so most of the stuff we buy is largely shielded from this "pass it on" scenario because of how competitive these markets are. Kind of messes up your whole "corporations pay no taxes, only the consumer does" argument.... Which, by the way, is just as tired and discredited as most other conservative talking points.
