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? 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.
