If my income matches my expenditure and I have £120 in savings then a £60 fixed penalty means the kids won't be getting Christmas presents.
If my income greatly surpasses my expenditure and I have £1,000,000 in assets then a £60 fixed penalty means I'll pay for the wine shipment on the other credit card this week.
It depend what you want your penalty fines to act as. If they're an arbitrary punishment designed to reimburse the Council/Victim/Whoever for the cost and inconvenience of the crime then that's fine. However, if they are designed to deter or to actually punish the individual then clearly the current system is skewed in favour of the rich.
I'm speaking specifically in regards to fixed penalties here, as opposed to fines levied for criminal offences.
Exactly. I think the key thing to determine is what is the intended purpose of the fines in the first place?
Outside of pay & display car parks, someone parking somewhere they shouldn't does not inherently cost money, so are these fines issued to cover the costs of issuing the fines? In which case, why not do away with the fines, because if there are no fines, there wont be any costs associated with issuing the fines.
If it's in a pay & display car park, then why aren't these fines simply for the amount a ticket would have cost for the time the person was parked?
If they are purely to make money, then why not make the fines higher? After all, it would be better to make £600 than £60!
