Why the whole world is going to improve under a multi polar world

Alright so most often there is a hue and cry about how the world will be a worse place once the US ceases to be a hegemon around the globe as there will be more authoritarianism, more conflicts, a new age of regional expansion, etc.

While I agree with all these statements I would like to go down a different route and point out to one feature of a multi feature world that everyone ignores. Increased competitiveness and civilizational growth.

As per one view of history, civilizational growth tends to be cyclic. I.e. peace time, decline, breaking apart, new growth, integration, prosperity, peacetime.

What this means is that every time a system of doing things reaches its peak, it breaks down and is then promptly replaced by something even better before that reaches its peak and declines and is replaced and so it goes.

For example- the largest empire if you go by land size was actually the USSR and in no other point in history did we ever see national level integration at that scale. It broke apart, and later we can expect something even larger and more efficient to take its place.

Now why is that relevant to a multi polar world. It is so because now we are likely going to reach a new age of expansion where countrues either integrate into continental powers, break apart, or are forcefully taken over.

"That's awful" you say, sounds like a world filled with constant bloodshed and violence. To which I say nukes changed the story. The countries that can now be invaded and territories taken over only happens when there is an extreme power discrepancy between two areas which highly limits the regions where such conflicts would take place.

On top of that we also have both the US and China pushing for increased, research, investment, and development all over the world to improve their situation.

For example, did you know that the belt and road initiative if placed on a world map displays infrastructure development plans all across the underdeveloped world? This is because the only countries generally willing to sign up for BRI are generally nations who did not prosper under American hegemony, so for the first time they find themselves with great opportunity for growth.

With a multipolar world we find ourselves with all the countries of the world seeing new growth and prosperity in a fight to gain their support so that the other side doesn't.

Thank you for coming to my talk. I would love to hear your opinion on the matter. Let's discuss.
