It's easy to make vague, unsubstantiated statements when you don't define anything.
Most establishments are gaining power. Right-wing authoritarianism is taking over governments in the US, India, and Poland. We are in a new Gilded Age, where people like Elon Musk can openly commit crimes without punishment and Peter Thiel can select Senate candidates. The CCP is gaining power and big banks are buying up cryptocurrency.
The only failing establishment I know of is organized religion, and even then, Islam and Christian fundamentalism are doing just fine.
