Having family members who are/were high powered lawyers (working for international firms, taking home 300K UKP per year or more), they certainly spend very long hours and lots of time in meetings, and certainly have to read a great deal in order to review carefully very long documents.

However I would make a distinction between hours spent in meetings, talking, and reviewing documents, vs. bringing as much brainpower as you can to solve a problem and do something new. Somehow the job of the scientist or engineer seems much harder - perhaps this is just my perception however.
