The goal is to extract enough to make the defendant take notice, but not cripple. This has always been a suspicious area: the power of the rule of law (predictability) vs. the power to hurt bad guys. You don't get all the protections you do in criminal cases, but do you want a bunch of amateurs deciding how much of a fine you should pay?
Ex post facto concerns: a lot of times damages are awarded in cases where it wasn't totally clear that they'd be penalized. It's theoretically possible to have criminal penalties as well, plus awards in multiple jurisdictions for the same sorts of acts. Also, in theory, we've compensated the plaintiff with plain old damages.
There's also this notion of the private attorney general: real criminal law can't cover everything, so we want bounties to make lawyers want to help out in this area. On the other hand, why make a lawyers-get-rich system? Who does that really help?
This is a US-only problem, pretty much, because we have relatively modest regulation and private causes of action. The theory is that only serious cases and ones involving crazed rich people will get litigated, and the market will take care of the rest.
Is there, or is there not a litigation explosion? We are told there is one, but research (Galanter) indicates that this may not be so. Not only that, but awards to plaintiffs are declining, in spite of inflation. But anyway, fear of the explosion has caused many states to institute caps on damages (these get attacked on the basis of constitutionality: the state constitutions allow you to sue for damages). 14 states have this (in many states, the cap is a multiple of the compensatory damages, in some, it's just a flat amount).
In product liability, you may be better off if you kill people, rather than make them need intensive care for many years. Atrocity stories are the counter-argument: corporations getting off cheap for huge awful deeds.
Anyway, there are some wacko jury verdicts, to be sure. At the same time, though, we have this notion that punitive damages have run out of control.
He sort of made a career on studying unconscionability. He is a real cynic. He asserts that you can shoot down nearly any normative claim.
Trying to regulate these things is basically playing games: the costs would just get passed on some other way, or the people will engage in a different business altogether.
What do you expect Walker-Thomas to do when the cross-collateral clause is struck down? The least thing possible: just add a sentence or a disclaimer, or something. It'll get litigated again, etc. This is a fantastically expensive way to implement policy: you just nudge teensy individual points around.
