Common meaning:

The state of having success financially.

Hidden meaning of the Equity religion: 

Success that is created for a few by extorting work from the many.

Discussion:

The Equityists believe that the rich capitalists prevent anyone else from having financial success. They extort the workers and keep all of them poor. No one can get ahead because the system is rigged.

The Equity believers are correct that the system is rigged against people, but the main reason for this is not the capitalists. It is life itself that causes so many issues and challenges. The natural environment and human biological limitations work together to make life very tough on everyone. 

There are no magic solutions to the difficulties of life and when believers claim you can blame everything on the capitalists they are trying to deceive you and perhaps themselves as well. 

Given that the idyllic dreams of heaven on earth promoted by the Equity faithful are not achievable in the real world, the best system we have to help deal with the challenges we all face is Capitalism. When it works correctly, capitalism provides freedom, equal opportunity and a better standard of living for us all.

Hitler blamed the Jews for all of the suffering of the German people and we all know how that turned out.
