Honest non snarky question, why does it take 1,400 employees to sell mail order glasses, which are essentially a quasi-commodity product? Ideally, a whole lot of them would be brilliant people working on improving design, improving support, and improving the supply chain. Most likely, a lot of them are working on or administering the retail storefronts, which in 2018 is a somewhat a marketing function. Also more likely: A lot of them are working on marketing. The incentives of the investors and customers don't quite align. This misalignment vector generally expresses itself through the Marketing, PR, and legal teams.
