It does make it sound like there's a bribery-free equilibrium really close by though. Like imagine all of these things happened as part of a single reform:
- Policeman and management salaries go up.
- Fines go down.
- Taxes go up.
- Anti-bribery enforcement goes way up.
The idea would be to acknowledge that regardless of the bribery culture, the typical policeman might be doing a decent job and doesn't necessarily deserve an effective pay cut. The amount of money they're getting today is in some sense their "market rate", and the goal is to improve the efficiency and transparency of the system in other ways without shifting that market rate. Likewise the goal would be that the tax increases for citizens would be designed to match what they're paying in bribes and fines today, so they wouldn't actually end up paying more.
I assume the hard part is that each of these things by itself might make the problem worse, and it's only if they all change at the same time that you get a coherent result that's "good for everyone". And there are probably a ton of other factors to add to the list. (Like tax enforcement. Is it even possible to raise taxes to accommodate salary increases and fee decreases? If the tax code needs to be reformed before people will accept stricter enforcement of it, what are those reforms, and who would fight them?)
