What is the difference between the medical profession and the legal services profession? It is just as pricey to become a lawyer. Yet even lawyers have the concept of "pro bono".
True. Perhaps it's because medical school is harder than law school. Or perhaps because if a doctor gives free medical advice, and something goes wrong, someone could die and he get sued. If a lawyer gives bad advice, the typical downside is not as bad, plus, a lawyer is less afraid of getting sued since he can defend it against better, cheaper, more efficiently. Just brainstorming aloud.
