Seems like you need and try to convince people around you to vote for a party that wants high taxes on the rich (that include wealthy politicians), transparency on public expenses, public data on politicians resources, democratic control/revocation of elected representatives/public servants ? And forbid money owned medias by controlling their finances too ? There are only two ways to take down an oligarchy, a revolution and its unavoidable oligarchic backlash with the help of antidemocratic violent forces or use of the Democratic tools that the oligarchy had to concede throughout the accidents of history to divide it further and reinforce democracy. You will find it is quite hard though.

Abuse of taxes is not a party-specific issue. Until laws are passed to prevent this (which is probably a multi-decade lobbying effort), it will re-occur. You are right, it eventually boils down to "it is quite hard".
