They might've had ups and downs, across centuries, but never managed to even remotely compare to the sheer level of corruption we've seen in less than 2 centuries among republicanism, parliamentarism, democracy, however you'd want to call that.

Corrupted dynasties wouldn't last, couldn't last, never lasted in fact.
To don't be corrupt (= which would mean stealing from themselfs) was a point for any decent monarchic system, as it guaranteed a smooth functioning and a deeper organization as more control layers were added.
Now, well, you have lifetime politicians becoming an even more detached class than nobles and kings, without even half of the responsabilities for their actions.
A King might've answered to your (social, collectively intended as) needs, a politician pretends to care about you once every 4 to 5 years, openly lies to you whenever it doesn't outright mock your claims, and business goes on as usual.
