That's why I mentioned that we need to increase the cost of corruption too, but on the salary point. A state rep in many states makes minimum wage. So they need a day job vs doing their civic duty. A house rep in the US Congress doesn't make enough to have one home in DC case in point AOC, and many others who need to have apartments or live in their office, I don't know about you but I would rather have a house rep not sleep in a sleeping bag before voting on approving a low-level cabinet position that may be the voice of reason that stops the US from doing something dumb like invading Iran on Israel's and the neocon's orders. Or signs off on a bill that could be the new Jones Act that kills US commercial shipbuilding. Politicians aren't holy men they need to feed their families, many US presidents weren't billionaires. Case in point Grant, and Truman.Bear in mind how Trump has used his charities/foundations/etc. You absolutely know that in Trump's mind that they have given him a 747.
Bollocks. The president of the USA is a fucking billionaire, and he's grabbing everything that isn't nailed down. There are undoubtedly some politicians who would be less inclined to corruption were they paid more, but there might not be that many of them, and you need to face facts that a ton of politicians, like the current president, will stuff their pockets no matter what you pay them.
You don't deal with corruption by buying the fucks off with massive salaries, you make it institutionally difficult. You enforce accountability and transparency, and you scrutinise the shit out of everyone with utmost vigilance. SCOTUS haven't been bothering, and that's why they're accepting kickbacks left, right and centre. The President is going wild because SCOTUS have declared his corruption none of their business and his party in Congress refuse to even acknowledge there might be a problem, never mind act on it. That's why you're corrupt as fuck. Your elites have decided that they aren't interested in policing themselves.
I also would like to mention that your recommendations rely on an engaged citizenry, which isn't a constant. Whereas once you put in say a minimum wage increase or a state rep pay increase it stays generally for a long time or will get increased. As for elites policing themselves, there is capital/'the rich' bribing people in EU and European capitals like the UK, Russia, Germany, and France they just occur more slowly but America's fate will one thing be Western Europe, Canada, NZ, and Australia's fate as well. As for Trump being a billionaire, he's an anomaly. Most US presidents aren't billionaires in the 21st century.
