Well, your assumptions are wrong. I don't think the US is always right.

For example, I think the invasion of Iraq was stupid, and I spent much of the 2000's arguing with neocons on how stupid it was.

Or for example, I think Ronald Reagan's policy in the 1980's, where he supported tin pot dictators and murderous rebel groups in Latin America was stupid. Not to mention arming the future Taliban and Al Qaida in Afghanistan. Boy, did that come to bite everyone in the ass.

And yes, I agree with you that the US dollar as the reserve currency gives the US certain advantages, such as the ability to print money. On the other hand all this money that is printed is immediately gobbled up by the likes of China. The US dollar is seen as a currency of stability and a keeper of value. It's no wonder you go to countries around the world, and they would rather have you pay in US dollars than their own local currency.

Robert Mugabe in Zimbabwe was one of the only few people to jump on Gaddafi's pan-Africanism. He was an economic genius, who turned the inhabitants of his country into zillionaires overnight. And that's not a good thing. In fact, inflation in that country got so bad they ditched their own currency, the Zimbabwean dollar. Guess which currency they adopted? The US dollar.

I try to stay consistent and base myself on facts, and not see a conspiracy everywhere. Unlike people, who are ideologically driven first and foremost, whether on the right or left.

And yes, I agree with you that countries (or sometimes their leaders) are trying to look out for their interests. Sometimes these interests are good for the country, and sometimes they are only good for the leader (as Putin has proven).

Do I think BRICS is a viable alliance? I don't think so. Their interests are too different, often at odds with each other. Russia has written itself off now, and so only China is a country with viable global clout out of all those countries. However, it can only maintain that clout if it keeps good with the main sources of its money, that is the US and Europe. So it can't shake the boat too much, otherwise it will lose money. Not to mention the fact that China and India are not friends, and even have armed conflicts with each other from time to time.
