Do you think that government representatives truly represent the people or are they more interested in taking care of themselves and their friends and contributors? why or why not?

I don't.

Explanation:

Representative government doesn't represent most of the people, and that's not actually bad at all, because one thing is people power to vote and decide, and other thing is that people are able to take those decisions. Ignorance inherent to the crowds.

Also, representative government concentrate power in some electors which vote have more value that normal people, this guarantee more power to those electors.

Taking care of themselves an their friends is a common action between politics, no matter what perspective they use to rule. Always is gonna be family and friends first.
