And, hell, if it takes a CEO to decide what "modification kits" to produce, and a scientist to produce them,

This is different than what you seemed to be implying in the grandparent since in this scenerio no one's forced to apply the modification kits to themselves.

it might turn out slightly better than any random people with random ideas trying to impress those upon their social lessers and dependents.

Well, that depends, is the CEO subject to market pressure with respect to the kind of "modification kits" his company produces?

If so, then this basically amounts to self-modification, and has all the associated benefits and problems, e.g., wire-heading.

If the CEO isn't subject to market pressure and the modification kits are forced then I would find this much worse than mere social pressure.
