OP what do you think, why do politicians fight to be in the government? It's not because of the salary that prime minister gets, it's because they want the power. When they have the power, they look at the world like a chessboard.
in many cases its not about the salary to play the current game of chess(be PM) its to use the current game of chess to win the game for whomever(lobby group) bet the highest amount for a certain side to win. and collect a good golden prize at the end of the game (lucrative business deals with lobby group after being PM)
we even seen it happen in the bitcoin world
years ago a US regulator in NY state created the "bitcoin licence" which put hurdles in the way of businesses and citizens in NY state. and as soon as he implemented it. he resigned and then become a "consultant" to aid businesses into how to get the bitlicence and he milked businesses for the privilege to help them get passed the licence he put in their way
