I think wealth-based fines should apply to cases when there isn't a specific financial benefit from activity in question. Ie I can see the argument why speeding fines should be wealth-based (since we can't really quantify what the personal benefit of speeding is). However in the case of fare-dodging, the fine should be directly tied to the benefit derived by the dodger (multiplied by an estimate of his being caught). Since that number is fixed regardless of one's wealth, I don't see why the fine should vary. Ie you can only make that argument if you are willing to assert that metro fares themselves should vary based on one's income (and by extension all govt services). The counterpoint is that wealthy people are already paying more via taxes :)
