For instance, I was fined for not displaying a parking ticket. But I took a picture of the machine that wasn't able to process my payment. I emailed picture to the appeals process and was forgiven the fine. Which essentially meant I got to park for free (shiny sticker)
If someone is trying, even if they fail, that means they are more likely to improve if they receive the right sort of feedback or support. Someone who isn't trying lacks even the basic motivation necessary to try.
Instead, if you treat someone who tries and fails the same as someone who doesn't and fails, then there is an incentive for the person to not even try!
For your parking ticket, if you geniunely tried to pay a parking ticket but couldn't (for example because you didn't have the money at the time) it totally doesn't make sense to charge you double. It would make more sense to do something like put you on a payment plan, or otherwise take into account that you have legitimate difficulties. Financial, organizational, or otherwise.
Zero tolerance policies do not "solve problems" because they ignore the individual contexts.
I, an adult of sound mind and stable finances, occasionally forget to pay parking tickets on time. I am punished by a doubling of the fine. I deserve that punishment by breaking the law a second time, and I pay for that violation of the law by paying the double fine. It sucks but I move on.
These edge case straw-men are not a productive retort to my statement.
Many Americans spend basically their entire adult lives with outstanding fines against them, if only because it's not possible for them to ever pay the cumulative fines + subsequent punishments. Throw on issues like bail and you've built a system someone can fall into and never get out of
The judge or magistrate reduced the fine by the maximum amount they could when I explained that I had made a simple error while trying to follow the parking rule.
There are different purposes to different activities. Teaching kids how to learn, for instance, anticipates a different outcome than chastising people for antisocial parking.
Or do you believe yelling at sick children until they get healthy is the proper approach?
EDIT: People, I said nothing about children paying parking tickets or about poor people. My comment is an example of a self-inflicted problem that is exacerbated by self-inflicted delay, to which the consequences must be borne by the individual as is the nature of life - NOT a dissertation on poverty. These distractions do little to serve the debate.
