It’s important to realize that in most democracies this isn’t a bug, it’s a feature of the system. The founders of these systems wanted to ensure that major decisions were deliberated, not rushed into, and that there wasn’t a lot of room for an executive power to make snap choices that would determine the future of the nation.
A company cannot disrupt itself. Sears, Kmart, and their colleagues who have perished became particularly good at making a profit through one specific channel. So every executive, every performance bonus, in fact every person on the payroll was focused on maximizing their specific method of turning a profit.
Unfortunately for them, the world changed and the leaders didn’t realize they were themselves being disrupted and therefore had no capacity to turn the titanic.
