I'm not saying that there aren't problems with the system, and a few problem lawyers to go with it, but it's far more exaggerated than you'd think.
Think about it for a moment, Pablo, you're a business person, obviously. If I came to you and offered you a proposition under which you'd put forward somewhere between 15k and 50k of your own money as an up front, with the promise that you might get your money back in around five years (with no interest), and the probablility of getting it back depends upon the the generousity of six strangers who hate you, desipte not having met you yet, what would you do? Invest? Would you invest on the chance of having a longshot, oddball positive outcome??? I doubt it.
Look, I did this work (and criminal case defense) for ten years before being recalled. I, and the vast majority of reasonable and sane lawyers, don't touch truly frivolous cases with a ten foot pole, because if we did, before long, you've lost all that time, and all those costs you've advanced (the 15k to 50k, I mentioned above, which is a range of what's typical). Forget the boat payment, you lose the boat (no, I never had a boat in the first place...). Every once in a while you get an oddball result from a jury, but most of the time, they're made up of guys like you -- folks who wouldn't give their grandmother a dime for her medical bills if they had run her over while not paying attention -- just because it's a court case.
I make very careful, well reasoned business decisions about which cases I take and which ones I don't. I assure you that if you ever see me in a court of law, and hear one of my cases, you'll be scratching your head and wondering why the insurance company didn't pay up a long time ago.
Gents, perhaps we should judge individual cases upon their merits, not on whether we dislike some iconic (and largely fictional) vision of what lawyers are. I wonder how any of you will feel if, heaven forbid, you end up someday hurt, screwed by an insurance company (or perhaps a Ford, GM, etc), and in front a jury of people who, like you, are convinced before they ever arrive at the courthouse, that your case is a frivolous fraud.
