?? Not sure I follow your logic? Does one necessarily need to be a multimillionaire to control a large body with many employees?
I spent some time in the USSR before its demise to work with some scientific colleagues. Seeing both their small town and central Moscow convinced me that a central bureaucracy was very inefficient at investing capital. I'll put up with a certain amount of excess wealth to get a variety of investment strategies.
True, although the dream is a solution not dependent on bureaucratic structures nor the whims of the few. And I would argue that the cirrent solution isn't particularly efficient in figuring out its investments: investment seems to predominantly gravitate towards real estate speculation, luxury apartments, tourist traps and hoarded wealth (e.g. capital stored in private art collections) and not on relatively unsexy things like infrastructure etc. I could be wrong there as well.
I suspect you are here, if only because the guy who quietly invests in a toll road, or collects dividends from Proctor & Gamble doesn't make the news much
