I think this is linked to how much rich people have bought a country.
If a politician is working for the people, then there would be a lot of trust.
If, on the other hand, a politician is working for rich people, then people won't trust them.
It really shows. When you hear a politician trying to sell and idea that doesn't sound right, you just know there are some back door deals going on.
When you listen to an honest politician that actually wants to help people, it's refreshing.
