I think it's unlikely to be the next big systemic change, but maybe after a the next one or after the US balkanizes. We already had one business-military coup last century but it seems to have been brokered and didn't really pan out exactly as the coup plotters intended.

Nowadays power is slightly more diffuse but with lots more hollow wealth, so when there's a big shock we'll see some incredible consolidation of power and maybe, maybe, a possible revolution in reaction to that.
