Leaving a second comment to provide another perspective.

The more your wealth (and note that income is a crude approximation here), the easier your ability to pay. Hopefully you agree that a $50 parking fine means virtually nothing to a billionaire; it may as well not exist. Whereas to someone living at the poverty line, it is incredibly significant.

If you feel it's fair to penalize everyone the same absolute amount of money, that means you believe that rich people have effectively earned themselves a right(!) to violate laws that poor people can't afford to.

Or, putting it more bluntly, it means you think rich people are superior to poor people.

Is that fair?
