What doesn't the U.S. understand about BRICS?

The United States' main influence in the global economic spectrum is through its inclusion in the G8. Considering that the G8 is a group of all industrialized countries, they have come to underestimate the power and capabilities of BRICS. The U.S. has failed to understand that the fast growing economies and development that is currently taking place within all the countries that make up BRICS provides them with the potential to acquire power that will ultimately position them above the G8. The G8 and BRICS should join together to collaboratively tackle global problems.
