Demographics alone won't save any country if too many of its people end up favoring slimeball liberalism and scumbag liberals. Look at Eastern Europe when it was part of the hard-left, ultra-liberal Soviet bloc.

However, I will admit that when leftwing social, political, economic dynamics are pushed on a people and place, the demographics had better be damn naturally stable, responsible, resourceful, talented and humane. Or else such a nation will go down the leftwing toilet even faster, quicker, meaner and harder.

Nonetheless, the hard-hearted, misery-laden, ultra-liberal Soviet Union did manage a fairly impressive space program, TASS. But everything else about that hard-left society was shit.
