Earlier quoted context omitted.
Umm no. Not all lawyers. They do take time because they want to win. And sometimes they have to be sure as some cases can be complicated.
Ummm unless lawyers somehow have evolved different brains than the rest of us, they, too, prefer to make more money vs less. So if they are billing hourly, then yes they all do want to spend more time. Now, they might fight against that urge (E.g. believing that spending less time on Client A will improve their reputation and lead to more clients) but your statement is naive re how incentives work
The only thing hourly billing does is shift the risk to the client.
