Sure, but in this instance the person you are metaphorically telling that to is the person who is paying half the costs in their capacity as a taxpayer. If there is a scheme that is cheaper than incarceration for 3rd parties and gets everyone to court on time then I'm sure everyone is in favour of it except maybe the bail bondsmen.
But the status quo is defensible - "rich people shouldn't be privileged" isn't a sensible argument. They have to get some comfort out of all that money. That is the point of money - to buy comfort. Lots of money = lots of comfort. Many people get rich through exceptionally hard work and it makes sense that they get something out of it.
If they can't buy comfort with money then there really isn't much point to it.
