Not knowing where you live, I am unable to compare. I do know that the term, "frivolous lawsuits" is a highly subjective one and I also know that the term is most closely associated with conservatives touting "tort reform" - which is conservative code for freeing Big Business (in this case, the medical industry) from responsibility for its negligence at the expense of the individual.
Now, having said that, I will readily admit that there are indeed such things as frivolous lawsuits and ambulance chasing lawyers. I will further agree with you, that both are a pox on our society and should be ferreted out and corrected whenever and wherever possible.
However, I do not think that "frivolous lawsuits" are responsible for a significant amount of national, medical costs. I have heard a figure of as little as 2% or less.
I know that trial lawyers, in general, perform valuable and honorable service in the prosecution of civil (and criminal) litigation and I submit that whenever a trial lawyer is paid a fee at the conclusion of a case, it is almost always well earned.
To answer your concluding question, yes, I am an attorney.
