You are right. That's because the world is still under the same capitalist system, where the imperialist powers plunder the oppressed countries. The same systemic order is mirrored in individual capitalist countries, with the ruling capitalist class plunder the oppressed masses.
The difference is that cracks are appearing in such capitalist world order, with China and couple of more countries escaped (too bad the USSR was sold out from within). There are also cracks inside those capitalist powers, with the oppressed masses demanding their rights.
Such oppressive international and domestic order breeds crisis, and the crisis are getting more and more acute, and may burst into flames and even explosion. The order may not last another 120 years...
That is not what is going to happen my leftist friend.
What is going to happen, will happen a lot quicker, probably in 10 to 20 years the world could be re-made.
Watch this video, and this guy tells the truth, the part about how the Chinese does REAL business, that it was real business and they did not need the state's military behind to do it, unlike the west, which was exploitation and colonailism.
It is win-lose versus the win-win.
