“Close the law schools for 20 to 30 years.”
Pass a National Law Insurance Act. Change the laws making it easy AND profitable to sue lawyers for malpractice.
That might work.
You can sue lawyers for malpractice now. It happens a lot. Also you can make complaints to the bar of their state. Furthermore, there are sanctions available in Court for instances of frivolous or harrassing behavior.
There is a great deal of anti-lawyer populism that fires people up but which stretches the truth.
