As Americans, we accept a certain level of corruption, lies, unaccountability, etc., from our politicians. Always have. It's obviously imperfect, and we should do better. However, this has always been the case, and we've still managed.
Trump is an entirely different level of these things. And one that is completely unacceptable, provided we still have any pretense of remaining a democracy or being a "country of the people." Trumpism is unsustainable, at least if we are to remain a constitutional republic.
