HAHA that last post is hilarious/ridiculous.
I have worked in BIGLAW and boutique law. I can honestly say that a successful sole practitioner makes just as much if not more than many attorneys at BIGLAW firms. On the other hand, Learned Hand is correct in saying that the business side/BS is a headache. Accounting, people quitting on you, firing people, hiring people, marketing yourself, etc. It is tough being your own boss, but if you can hack it, the rewards can have unlimited potential.
