A system could be worked out that reduces that inequity - A tiered system like income tax would be easy to apply. A system that charges based on a fixed, high percentage of your income above a certain threshold (e.g. the living wage) would ensure that offenders lose most of their disposable income for a period, regardless of their wealth, and that they don't risk eviction and starvation, regardless of poverty. Of course, if, due to your lack of spare cash, you're stuck in your mansion, swimming in your own pool, and unable to replenish your comprehensive cellar of fine wines as you drink through them (until your fine expires), it's still not as much of an impact as being stuck in your flat, unable to buy admission to the municipal pool or buy a single can of Special Brew; but it's fairer than a flat percentage, which in turn is fairer than a flat penalty.
