Not so long ago you didn't need to ask big law firms what they stood for, you pretty much knew. Those who reveled in the leveraging model and celebrated their rankings in the tables, pretty much told you they were in the business of making the partners rich. In those days, ESG wasn't a thing, and PEP was everything. 

In those firms, the prime purpose of associates was to record time, often at the expense of evenings, weekends or anything resembling a life. What the work was didn't matter; dull, monotonous, or even barely relevant. Eat it up, release the time, repeat.

If associates had their place in that era, so did clients. Their prime purpose was to produce chargeable workloads and then pay the bills. Law firms had control.
