Some propaganda:

Tho OPs pic's point remains - SW is a space western & can't give us the full picture of how the average world lived under either of systems, but going from widespread and generational corruption (not just the Jedi, but starting there) to a single point of power (dictatorship) initially lowers the corruption & dethrones (or recruits in diminished way) various mini-powers/leaders/mobsters bcs if nothing else they are simply a threat to the image.

At any rate, never be ok being governed by a 900 year old unelected frog that can't spot a Sith Lord if they shared a urinal at his visit to the senate (and the frogs religious zealotism is centred around genociding said Siths).
