And then there's the flip side (overly simplified, of course):

1. All politicians are corrupt.

2. Therefore, I will not support any of them.

3. The more people are disgusted of general politics, the easier it is for a corrupt politician to gain power.

4. But that's not my fault, because I never supported the elected one. In fact I never supported any of them!

5. Wow, this country is really going to shit. Go to step 1.
