In a lot of law firms, the resistance to change is simply because completely changing workflows is not easy to accomplish. They have a lot to do, and given their system works for them, you need to demonstrate the advantages for them. Show them why this will make their lives easier. They wouldn't really make less money, since if they are really spending this much time, it's probably time they could spend billing two clients instead of one (usually better to run up two small bills instead of one large one).
In any case, this is true in trying to change any enterprise, law is no different.
I converted a group of lawyers, who were still using Corel Wordperfect for drafting multistate legislation, to using an XML based workflow, after showing them why it would make them faster, not why it was "better for the world who was trying to look at drafts".
Imagine you used emacs all day, every day, and then someone came in and says "we're all moving to VIM".
Personally, I do all my drafting in text and use version control, but use word as an interchange format when stuff goes outside of the company.
