Municipal workers and bus drivers were right at the top (and it's impossible to get official information for those; they'd put together lots of different sources)
There are sunshine laws in US to prevent this kind of thing. Not sure if it's US in general or just California, but any money paid to any state employee is a matter of public record. So newspapers can easily make searchable datablases like this on their webpages. There was one for UC system (California's top public university system), and that one was a lot more reasonable. Aside from top management, people getting the most money were famous professors, and the overall level of salaries was pretty reasonable. Actually, it looks like they now have all state employees in their database: http://www.sacbee.com/statepay/ (If you are curious.)

and at the bottom, teachers and specialist doctors working in public schools and hospitals.
The teachers aren't payed much anywhere in the world, but I am a little surprised about doctors. (In post-Soviet Russia, doctors are also payed so little that they have to make up for it by "charging" patients directly, but that's more a factor of messed up economic situation and corruption so widespread that it's considered a normal business practice.)
