From expertlaw.com:

"Most medical malpractice attorneys take their cases on a "contingency" basis, where the attorney fee is a percentage of the amount recovered from the defendant through judgment or settlement (usually 1/3 of the judgment, after costs and fees are deducted). It is unusual for attorneys to take malpractice cases on a "retained" basis, where the client pays the attorney fees and costs but receives the entire judgment or settlement, as few clients can afford that option. In many malpractice cases, by the time a case reaches trial, costs alone can exceed $100,000.00." (emphasis mine)

According to the US Justice Department, 25% of all doctors across the country are sued annually.  That's a one-in-four chance of being sued each year.  If that were the case with lawyers, I doubt that very many of them would be paying $2,000.00 to $3,000.00 per year for their insurance.

Insofar as the $100.00 hammer analogy is concerned...the fact remains Medicare is alive and well...operating within the confines of current funding. We are not buying $100.00 hammers here.

In what parallel universe is that happening?  The Medicare system is in serious financial straits and is expected to collapse by 2019 at current spending levels.  It will cost over $85 trillion to fix the problem and will make the mortgage industry bailout look like pocket change.
