Politics in a Democracy involves a lot of stealth corruption. The other alternative which is a dictatorship by one guy isn't that better as nobody ever wants to relinquish power and there actually is visible corruption.
At least with Politic in a democracy people feel better as they get to feel like they have a say and feel they are involved in what's going on yet corruption is still there playing a huge role.
Mtw if you are really depressed by the current state of the world here is what you can do.
1. Focus on your own mess that's Polish politics before moaning about the USA, France or UK.
2. Declare your home a Sovereign State and you won't need to worry about any politics except your own
Of course you will be soon in the News as a big Joke before Corruption decides to lock you in jail.
