As to the solution... I'm not sure. 'Loser pays' might be a good start, though people will argue 'but that lets deep pockets just bury lawsuits'. Yeah, but that's happening now. Judges are not doing their due diligence in looking at these lawsuits and going 'What the fuck is this shit?'. And the problem's been going on for a long time -- I recall John Stossel complaining about it 20+ years ago. You don't even need to be a lawyer; you just need to know enough of how the legal system works and you can fucking terrorize people.
