Why would you gamble with your freedom? Most of Paul Graham's fans could easily do 3 years of lawschool at a top tier school and could then work 5 years and retire for life.
Typically, you're about $160k in debt from law school, so the first year is spent paying that back. The next 4 years taken together is only $795k, nowhere near enough to retire for life. All the associate years together is only about $1.6M, still not enough to retire after 11 years.
Then you have to make partner; if you don't, you're out of the firm and usually have to set yourself up as a sole proprietor. If you do make partner, you're set for life, but at 11 years getting there, the road is nearly as long as becoming a tenured professor and usually longer than becoming a successful entrepreneur.
