The statement is too vague to verify as a factual claim: it does not define what counts as "the establishment" or how much collusion would be enough to make it true. The 2011 context did include real public concerns about lobbying, undue influence, and blurred lines between ministers, lobbyists, and officials, including Parliamentary discussion of Bell Pottinger and other access scandals, but those examples do not establish that "so much" of the establishment colludes as a measurable general fact.
