This wouldn't change if the salaries went up 10x, or even 100x.
Influence is worth far more than cash ever could be.
The expensive part is GETTING elected, not serving. If you don't have the resources to win, the salary doesn't help you.
I don’t have any data to inform my decision on what would be the best number though so I should shut up.
The reason to oppose it can't be "I can't afford it". It's more "those bastards don't deserve it". And that's not how mature adults should think about things.
Compared to the impact the federal government has on all our lives, it's nothing. If it resulted in 1% better governance, it would be a really well spent $15.
$10M is 8 figures.
I agree it's high :) $1M might be enough.
A higher paid politician is also less likely to be corrupt (since the agent causing the corruption will need to beat their high salary, which is risk free). A higher paid politician will not need to worry about blowbacks from policies that are good for society but bad for existing entrenched players.
And a higher paid politician may encourage people, even if they were poor initially, to work to become a career politician (and study it, the same way a neurosurgeon or any other professional trade would). High pay almost always equate to high intelligence, and i would hope that an intelligent person is also someone who can run things better.
Also, remember that this is "in exchange" for anyone who assumes office to mostly forgo income from individual investments and I'd add things like book deals and honoraria after office. Someone mentioned Singapore and that's my example case here.
