No it's not. Those 10% are all independent actors with individual and private interests.

I'd much rather the economy be controlled by the top 10% of a productive society than by the 1% of a bureaucratic structure.

and the former Soviet union wasn't a system with independent actors with their own interests?

people seem to think the Soviet economy was ran by a single person decided everything about the economy. while in practice its actual implementation was rife with personal and organizational infighting to reach Stated or unstated goals.

How about we let more than 10% control the economy? One would think that the ideal of a free market at least exists to involve as many participants as possible.
