> They generally don't and won't stop until there are real repercussions for that, like losing your political career/being canceled in society over voting for it.
I wouldn't call login political career or being cancelled and voted out "real repercussions". They can pretty much retire and enjoy the rest of their lives with all the lobby money and EU rents.
Real repercussion would mean prison time and losing their property, but we all know that won't happen anytime soon.
