ELI5: If all people openly know that most our top leaders are corrupt, why don't we just get rid of them and get new ones?

Every day you hear someone widely making a comment about the corrupt Government officials just making all the money and leaving the rest of us like crap, and we just accept it. With this information being so open, why don't we do something about it?

In every country this is true. It's even the butt of most jokes that all politicians are liars and thugs. Again, if everyone in the world knows this, why is it so hard to straighten them out?

(I know my post seems redundant but I really want to reiterate how it's a common topic of conversations. Before you answer, do you trust all the politicians?)

It's important to remember that in a democracy, we are almost always putting our politicians in no-win situations. 

Spend too much time in Washington? He's a "Career politician and Washington insider." Spend too much time at home? "He's missed X votes this year. Why isn't he doing his job?"

Also remember that if an issue becomes a political issue, that means there are two sides to it. If there was only one obvious side to an issue, it would be resolved quickly and quietly. Which means that for every single issue that reaches the government, ***there is a built-in constituency that is going to be opposed to it no matter what you choose***. No matter what, every vote by every politicians on any sort of notable issue is automatically going to piss off 30-50% of the people. 

We expect our politicians to think about the nation as a whole but also for the constituents. Can't reconcile the two? Out ya go!

We don't want career politicians and want to limit their terms...but when new, young politicians get elected we call them extremists. 

Only scientists should be making science policy? Great, then, let's only elect politicians who hold multiple simultaneous degrees in science, medicine, accountancy, bioethics, social services, law, and psychiatry. Good luck finding 535 people who exist like that and also willing to do that for 150 large a year.  

We expect our politicians to work 14 hour days and never take a vacation, while maintaining two residences and spending half their time away from their families. Oh, and for a salary that is a fraction of what they could be making anywhere else.

Basically, due to the very nature of democracy, we automatically hate our politicians. And that's OK. If you aren't criticizing your leaders, there's a pretty good chance you're living under a dictatorship.
