Do you know neurologist personally? Do you know his financial situation, or the details of his practice? You guys sure he's at the 50th, or even 25th percentile of income for his profession? What kind of family commitments he has? If not, then maybe you should avoid passing judgement on people you don't know--in case you missed it, it sounds like he was one of the few people around who was willing to see that patient population even under the old system, so clearly the guy WANTS to help that patient population if possible.
I'm not sure ultimately if this law is good or bad long-term. Regardless of what happens, I'm going to find a way to be happy in this profession making whatever I make. But to listen to some of you guys, it's like the only options are 1) Love the law and accept the decreasing reimbursements with a smile on your face, or, 2) You're greedy. You can pat yourself on the back for your shining altruism without arrogantly calling everyone who makes a personal decision greedy.
