Shoot corrupt officials.
The problem with power is that too many people want it and once they have it they don't face consequences for abusing it. The solution is to make it unappealing and risky enough to deter power seekers from acting out. No one would want to be mayor if you got potentially shot for fucking up and you made only above average pay. The only benefit would be if you actually had political convictions and goals beyond your personal enrichment.
You might get a few power seekers in the first level of leadership. You can't keep all of them out of course. But for each level higher you'll get less and less. People with political convictions are less likely to support the advancement of power-hungry assholes. The only way to significant power would be 15 years of risky, hard work with little material benefits. By that point, the ceo types would either be shot or quit to pursue more lucrative positions.
