CMV: all fines (or other monetary punishments) should be determined by your income.

fines should hurt people equally. $50 to a person living paycheck to paycheck is a huge setback; to someone earning six figures, it’s almost nothing. to people earning more than that, a drop in the ocean. a lot of rich people just park in disabled spots because the fine is nothing and it makes their life more convenient. Finland has done this with speeding tickets, and a Nokia executive paid around 100k for going 15 above the speed limit. i think this is the most fair and best way to enforce the law. if we decided fines on percentages, people would suffer proportionately equal to everyone else who broke said law. making fines dependent on income would make crime a financial risk for EVERYONE.

EDIT: Well, this blew up. everyone had really good points to contribute, so i feel a lot more educated (and depressed) than I did a few hours ago! all in all, what with tax loopholes, non liquid wealth, forfeiture, pure human shittiness, and all the other things people have mentioned, ive concluded that the system is impossibly effed and we are the reason for our own destruction. have a good day!

If you have a billion dollars, a 99% penalty for any given crime leaves you with 10 million dollars where as someone with a million dollars would be left with only 10 thousand by the same punishment. This is an issue with proportionality, even if you're paying the same percentage of what you have, the amount your left with in real terms is significantly different. 

I don't know how you could set something like that where it's equally punishing to people with orders of magnitude differences in wealth. It's closer to the same punishment than flat fines but direct proportionality doesn't go far enough.
