Your average farmer doesn't have the resources required to field a lawsuit against a multi-national company.

Then that seems to be a flaw in the law system. Still, even if they don't start it, why would the company win frivolous claims?

Surely you don't think that frivolous claims are never won?

Not sure, certainly they shouldn't be won as a rule. Maybe there are exceptions, but it shouldn't be just a case of whoever hires the most expensive lawyers wins.

There's a massive gulf between "shouldn't" and "isn't". :/

So basically you are saying the legal system (in the US?) is worthless?

Draw your own conclusions.
