Please do not equate the current
legal system with a
justice system. The system has to be based on law, and not justice, because everyone may have a different opinion on what is just and fair.
The courts system may seek out justice whenever it is possible to do so, but in my anecdotal experience, and in my exposure from [likely biased] sources, it declines to make the attempt, and seeks out simple expedience instead.
In cases where a jury may be employed to decide the outcome, the public opinion on how justice should work is relevant. If you are ever offered a potentially abusive contract, by all means consult a lawyer if you intend to proceed with it. But if you're ever on a jury hearing a contract dispute case, for the love of justice, please refuse to enforce a fundamentally unfair contract, where the party that drafted it refused to negotiate--or even explain--any of its terms.
