Leaning and a Question

For the last week or so I've been mulling over the role of government in relation to equality. I think many people (but not all) would agree that a government ought to promote equality, but I have been wondering what that means.

Should a government strive toward:
a) equal circumstance for all citizens, OR
b) equal treatment of all citizens, OR
c) something between

Economically, an example of (a) would be the bracketed income tax system used in the US. People who make more money pay more, people who make less money pay less. (Of course, numerous loopholes often defeat that basic premise.)

An example of (b) would be a flat rate income tax, like everyone pays $10,000 per year no matter how much they make.

And I guess the compromise between the two would be a flat percentage income tax, like everyone pays 17% of their salary.

My uninformed intuition is that the compromise is best, which is too bad. The other options are much more cut-and-dried and easier to apply universally.

Coincidentally, I took a little political quiz, via Jim. Here is my result...
