A jury isn't the free market
Perhaps I'm misunderstanding your point. It seems you're suggesting that lawsuits are an example of the free market in action. I don't think that's the case.
The free market is based on things like supply and demand, producers and consumers. I don't see that in the courtroom.
In some states, lawsuits are seen as a form of lottery. The operating principle is called "Jackpot Justice."
As for the juriors, well, ask 60 Minutes about that:
Correspondent Morley Safer asked, "The jurors benefit? Is that what you're saying?"
"They benefit after court, and everything is over with," Strittman said. "Yes, sir ... under the table."
