By the way, it's very interesting to see what BRICS will achieve. Them being strong will really reshape the global order but will it be for better or for worse? Will the quality of life improve in BRICS countries if they become less dependent on the western world? I don't think so.
Multipolar world is the normal world that has been the situation for thousands of years compared to unipolar world that is abnormal and barely lasted 20-30 years. So I believe that BRICS and generally any attempt at helping the establishment of an actual World Order is a good thing.
Whether the quality of life of individuals in each country is going to improve or not depends on the government the people choose. If it is a competent one, then yes it will improve.
For example read what I explained
here 4 months ago. Now tell me how many competent governments among the almost 200 countries in the world took advantage of such opportunities? (some users posted some examples in that topic itself) In this small example, something like BRICS can only help but it still needs competent people in office to actually take advantage and change policies, strike deals with other countries, etc. to improve things.
Both, multipolar and unipolar words have their pros and cons but I feel like unipolar will be the winner in the end. Globalism is inevitable to my mind because English is one of the easiest language (at least for me) to learn, it's widely spoken outside of China (and Chinese is very hard to learn for the rest of the world), informational technologies also connect people very much, the next generation grows less masculine (in a good way) compared to older generation, I bet less people want to go in war these days than it was before because today you have a comfortable life and there is nothing to fight for while in the past, the quality of life was terrible, people were less educated and were brainwashed with war motivations.
