An answer to your problem is isolated countries with strong local cultures and nationalism. Each country's population has a shared set of beliefs about what-should-be-done so they can implement it locally and the winners can impose their superior culture on their less successful neighbors. Hopefully not exterminating all different cultures and optimizing for short term gain though. We've always been doing this and still are. Islamic culture has some commonly agreed upon ideas of what-should-be-done and those countries implement it without being watered down by individualism. So does western culture but we've already done it and take it for granted so it's hard to notice. For instance, you don't see western politicians fighting to deny women the right to vote because we do have a common what-should-be-done idea about that.
