Change the voting cycle from 4 to 5 years.
Start with a minimum wage for all politicians.
Every voting cycle, their constituents get to choose whether it is doubled or flipped into a fine they have to pay, equal to double what they have earned so far, including any kind of bribes or compensation, past and future.
Every 5-year cycle, their salary may double. But the possible fine will also double.
Have some carrot and stick.
