That's very reductionist, and itself a kind of right-wing (authoritarian) idea - all politicians are corrupt so there is no meaningful way to change things.
Indeed. Aside from being extraordinarily intellectually lazy, bothsidesing actually enables corruption by failing to identify it, or failing to distinguish degrees of corruption that are so severe as to be more differences in kind than differences in degree. And thus in the U.S. we get Trump and his entire cabinet, Clarence Thomas and the rest of the Federalist Society, the Kochs, money pouring into elections via Citizens United courtesy of John Roberts, and much of the rest of the GOP political apparatus ... in large part a result of people staying home or voting 3rd party because their "principles" didn't let them vote for "the lesser of two evils".
