Before your ninja edit, you had a "(in 1994!)." The exclamation point implied that it may be more than 40% today.

Also, your argument is the strawman:

> My opinion is that lawyers do not add anything to the client's bottom line (but it doesn't matter what I think, only what the client thinks).

> But beyond that, it gets very subjective and very speculative. Needless to say, lawyers are very good at arguing the need for their existence and for their value to the client.

It was an economist, not a lawyer, who made the case for the value of lawyers to the economy.
