I really don't think people in local government are any worse or better than people working in X, for any X. If you think otherways - your choice, but would be nice if you show some proofs.
As a programmer you are making decisions how to use others people money (your code will, and you decide what it does). As an architect you decide how to use others people money. Same for lawyer, banker, insurance agent, business analyst, contractor, ... This is true for most white-collar jobs.
I don't see how you can think local administration clerks are worse and we are better. It's intelectually lazy.
In the worst case - local administration comes from people, and are choosen by people. They are on average only as corrupted, as average citizen.
> Do people want to look at buildings that are clearly just plain ugly? Do they want chaos and mayhem?
Yes. Apparently they don't care. As long as they get paid for that billboard, and it's legal - they are blind. Look at this:

Tell me with a straight face it's not out of control.
This is how my country loooks like now. It can be solved, because I've seen it solved in countries like Germany, Czech Republic (and to lesser degree even Lithuania or Slovakia). It's simple - you restrict billboards and advertisments in the city. No need for definition of "bad taste" in law.
Then there's simple bad planning (or no planning). This is most true in new suburban districts. Typical image: http://m.ocdn.eu/_m/45a8af04428ecb9e04a332883176027c,29,1.jp...
Randomly choosen plots, random road network build after the fact so that everybody has some way to drive to their house, no matter in how contrived way. Costs for building infrastructure much higher than if someone spend a month thinking beforehand. Again - chaos. And it can be easily solved with proper urban planning. It's not rocket science.
As for bad taste - this is harder problem, but it can also be solved. Just to show what we are speaking about:

This is understandable reaction to 50 years of gray communism, but still. At least the next generation will fix this with some paint.
