They are an economic/trade alliance. BRICS was formed with regard to mutual economic benefit. What is a "class of economies"?
No, they were formed as a class of economy. The term was created at Goldman Sachs to refer to economies that are big not because of per capita reasons, but because they have large populations. There was a flurry of economic papers about them, both in finance circles and in academia. A country like South Africa does not seem to obey the same economic laws as the Netherlands, but also does not obey the same laws as Rwanda. Brazil is large enough to actually have internal markets for most goods.
Later they decided to have a yearly summit to talk about their similar economic situation. There has been no trade or economic agreements, and many of the countries have very little trade with each other. In many ways it is a very random group made up of exceptions to the norm more than anything in common.
They are in opposition to the WEF and to its related corporatist ideology.
One of the similarities the BRICS have is a strong support for strong corporations. They intermix corporations and government power, with the corporations having a huge say in government, and the government having a huge say in corporations. The Latin American WEF conference meets in Brazil more than anywhere else. The African WEF conference meets in South Africa more often than not. The South Asian WEF conference almost always meets in India. And the East Asian conference literally always meets in China. The BRICS as strong regional powers have are well represented in the WEF... except Russia. Russia has never quite been able to break in. It is both too European and too not European at the same time.
BRICS, like Trump, wants economic nationalism
Maybe for themselves, but not for other countries. Do you really think China wants economic nationalism for South Africa?
BRICS are now working on establishing a trade currency that is NOT the US Dollar.
China has been able to create a currency that is relatively inflation free, but only by basing their currency on the Dollar. It is tied very tightly to the Dollar. The rest are messes. Do you think anyone really wants to tie their currency to Brazil or South Africa?
None of these countries want their currency to trade abroad. They like having strong control over their currency. That is often not healthy control, but that was already addressed in the previous post. How could a currency be a world currency if it does not trade globally?
Nah, they were just wanting other countries to pay them in rubles for their oil.
How would other countries get Rubles?
Russia will be just fine.
I have been to Russia a few times, and have never seen Russia be fine. I would not be surprised if Russia is not fine during my lifetime.
You are now in paradox. You literally just got done saying that this sort of thing isn't possible.
I said there was no current replacement for the Dollar, but if there was, it would not be all bad. There is no paradox in that.
You clearly do not recognize the main benefit of the US Dollar being the "petro dollar".
There are many prosperous countries in the world who do not have a world currency. There are benefits to being the world currency, but there are also problems.
