In western liberal-capitalist democracies, politicians are paid above average wages, but not enough to deter doing deals behind the public's back with real estate developers, corporations, and many expect a role in business after retirement from politics, in return for doing many favours during their tenure for those very businesses.
You could almost argue Singapore has a benevolent dictator, but that is definitely not true for Western liberal-capitalist democracy. Instead I find this article more descriptive: http://en.wikipedia.org/wiki/Corporatocracy
Logically yes, but practically there are many examples proving that increasing salary only have minimal effect or, in turn, increase bribe size. Just to name few examples:

Bribe size is increased, frequency is decreased, which is what you'd expect from increasing salary of a public official for the purpose of reducing corruption.
Take it to the extreme and increase their salary to USD$1m per year, and the frequency could drop to 0 or 1, and the price could be $10m, so fewer instances of corruption would happen because fewer people can afford it.
Public officials are also people. Most people have the same inherent desire to be good, and yet most are vulnerable to same temptations. The reality is not dictated by law.
Of course, good enforcement and punishment of corrupt behaviour is also required.
Rule of law and simple, transparent regulations are way more important than occasional voting. Especially if people can still vote with their feet.
Seriously though it is indeed concerning the way both major parties are heading with this, even if they had the best intentions its a nasty path.
Not sure. At least China gets investment in infrastructure done.
Less an illusion of accountability than a public intimidation tactic.
