Why do lawyers have the lowest job satisfaction?

I think it sums up the profession pretty well. Look, there are 200 ABA accredited law schools cranking out 50,000 new law grads every year. Law school is ridiculously expensive, many law schools are charging $45,000 a year in tuition, this is not even including rent or outrageously expensive books. Many students take out loans for the Bar exam. People being $200,000 in debt is not uncommon. Then you face the legal job market. Most attorney jobs pay $35,000-$45,000 with no health benefits. Some jobs pay $10 an hour or worse, others offer nothing to in exchange for experience. Unfortunately, thirty lawyers will apply for the bad jobs because they are unemployed. Don't believe me? Just look at Craigslist under legal employment for different cities.
