Okay, but that's a slightly different issue.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.
The argument you seem to be getting at here is that a politician should be paid appropriately to their expertise and responsibility. So, roughly equivalent to others with a similar level job (although I'd draw a line in terms of the high end of corproate pay and full remuneration). So for instance you could readily make a case that a federal senator should be paid a senior management level salary: maybe around the $500k - $1 million range? Then presumably the president more than senators and federal representatives less.
Given the need for politicians to work both in their home state and the capital, I would assume they should have relevant expenses: travel and accommodation (for digs appropriate to their station - e.g. rent of a reasonable size apartment in a decent area of town).
