Are our politicians looking after our best interest?

It's probably inaccurate to say that all politicians are corrupt and self-serving, but it is the type of profession that attracts the sort of person who definitely should never be allowed to do the job. Bad politicians usually have a good line of bull, though, so they can con voters into electing them again. What doesn't help is that the choice of who to vote for is decided by in house by political parties, and not by the actual voters. So, all your potential electoral choice could be bad. There's a saying that goes something like this: "No matter who you vote for, the government always wins". Changing political leaders has very little effect on the actual grunt work of government that's done by the civil service or similar.
