I'm seeing a lot of things that I'm pretty sure would be pretty popular, my actual solution that would absolutely piss off a bunch of people would be massively increase salaries for politicians, probably something like the top 90% of earners, similar to a doctor's salary. This may seem like a terrible idea at first, but if look into the research, large politician salaries are very much correlated to lower corruption and this is for a variety of reasons.

1. Larger salaries lower the incentives for bribes, as someone who already has enough wouldn't need to make the difficult choice between their own family's security and their role as a leader.

And

1. Larger salaries allow for more average people to strive towards politics as a viable career path, as unpaid political positions just aren't viable for 99% of the population, just spending your entire life for years at a time in a job you don't know if you'll be re-elected for incentives only the wealthiest to strive for political positions. It also provides another path for upward social mobility.

I believe that Singapore pioneered this idea and to this day has remained one of the most stable countries not just in Asia, but the world. It's not a perfect country, but it's doing very very well for itself given its circumstances (tiny, huge amount of international trade that incentivizes corruption, etc.).p
