You propose that lawyers "work" toward a certain goal. In any individual instance, that goal either is or is not in the client's best interest.
If it is in their client's best interest, then your proposal is a nullity; it changes nothing about the attorney's ethical obligations.
If it is not in their client's best interest, then to do that "work" would deny the client effective assistance of counsel. That would constitute structural injustice.
It's a simple question.
It's a nonsensical platitude, spoken by someone who neither knows, nor is interested in knowing, the subject matter.
If you want to be taken seriously, learn something about the systems you're trying to reform before telling other people how to do their jobs.
Otherwise, seems we've reached an impasse, so I'll just take my leave.
Do you take issue with the latter?
