Is Transparency the Highest Good

In our industry, transparency is seemingly being used as justification of "sustainable" purchasing. I wouldnt argue that this is wrong, but it does beg the question, "who does it serve"?

Asa coffee company, its a means of trying to communicate proof that no one is being taken advantage of in the process of sourcing and serving great coffee.

Regardless, if something is self serving, can it ever really be the highest good?
