Generate text that refutes this claim: The rich are now also deterred  Another purpose of fines is to provide a deterrent. If fines are applied at one rate regardless of income, they must be low enough not to be un-payable for those who do not earn much money. Consequently, they are set so low that they fail to have a deterrent effect on the richest in society, who are easily able to afford to break the law.  This is especially the case when you consider the sorts of crimes that are punishable by fines, e.g. illicit parking and littering. These crimes have an indirect harm, and thus it is easy for the rich to consider that once they have paid the fine they have paid for the damage done, even though in reality this is not the case.1  1 Gneezy, U., Rustichini, A., 2000. ‘A Fine is a Price’.

punishment house would make fines relative income
This motion will have no impact on that problem. Fines must be set at a low percentage of income so that the people earning the least do not find themselves going without essentials (a fine for speeding that caused you not to be able to heat your house in winter would seem, with good reason, disproportionate!)  Consequently, whether the fine is £60 or £6000, there will always be some to whom paying the fine is not a problem, and who will happily pay in order to flout the law.
