I fundamentally disagree. While there may be outlier cases, the core of a democracy is the separation of powers: the judiciary, the executive, and the legislative branches. If an agent within one branch violates the rules, you have the legal recourse to appeal to the others. In an authoritarian state, there is only one pillar of power - meaning there is zero recourse for citizens.

Furthermore, I’m tired of the false equivalence some people in this thread draw between the level of corruption in democracies and authoritarian regimes. They are simply not on the same scale - if you ever experienced both you would know that.
