It's not secret and it's not a cabal.

It's the group of people who benefit from a collusion with governments (by funding politicians campaigns) to get constant protection of their profits through systematic, de facto or explicit, bailouts by central banks, and more generally complacent regulations.

Abolish central banking and have a gold-backed financial system and they mostly disappear. You can't cheat with gold. People who say it's fundamentally unstable and the cause for deflation or whatever have so far not demonstrated that the alternative is any better.
