Brics is basically the "we don't like the west!" club of countries that think they're entitled to being great powers for.... basically just cause.

Brazil is basically just trying to manifest being a fully developed industrial economy, Russia is clinging to the dying scraps of being the second great power, India has all the potential, manpower, and material but is currently hanging itself with a nationalist noose in terms of being able to so business with anyone besides maybe Surinam, China tries to act like they're not bothered by having to do work to achieve international standing but VERY OBVIOUSLY resent that the world hasn't just reverted to the pre-age-of-colonialism status quo of China being the top of the world in terms of trade, and South Africa has apparently collapsed five times since 2020 alone with how many headlines you hear about it.
