What percentage of the cost of healthcare in the U.S. is the result of greedy parasitic lawyers and frivolous ?

God forbid that a person who is injured by the negligent conduct of his doctor be compensated for it. The cost of frivolous lawsuits is a myth. Frivolous lawsuits can easily be thrown out of court, and a lawyer is not going to want to pursue a case that will not be successful. It is the meritorious lawsuits, where someone is seriously harmed, that cost the doctors and/or their insurance money -- and they should.
