It's fairly universal that politicians are underpaid relative to the level of responsibility they hold.

I'd quite like my country (UK) to be run by folk who are competent, rather than by only those who can afford to run for office without being paid for it. Yes, MPs get a lot more than the median income. But many people who are well-qualified to be MPs are also well-qualified to hold roles that pay at least as well if not more, and without needing to run for election to get the job.

Taking the CoL in NL, particularly the Randstad area, that salary is not outrageous. Especially, if you're a new expat on a single income, without any social net, and with any hopes of owning property, within a reasonable commute distance from your work.
