Here is a question to ponder:
The idea behind fines is mostly to deter unwanted behaviour: ranging from graffiti to oil spills. In this sense, they are distinct from compensation payments, which are intended primarily to restore the victim of an inappropriate act to some semblance of their former state.
Given that the aim of fines is to deter, it seems that their size should be calibrated so as to have a comparable effect on all people. The effect of a $50 fine on someone earning $25,000 a year is different from the effect on someone earning $75,000 a year.
The question then is whether it is appropriate to index fines to some measure of a person’s monetary status? If so, is it more fair to base the level on income or on wealth? Each could produce injustices. In addition, should there be bounded maximums and minimums for fines, even after monetary considerations are taken into account? Also, should there be any distinction between fines levied on individuals, when compared with organizations?
