The size of the government is much larger than official state expenditures.

There are obvious cases such as the BBC - its license payer funded, but they are forced to pay by the government.

Then there compliance departments and lawyers who exist simply to help businesses adhere to government laws.

Finally, there are all the businesses that exist in service of government created problems. E.g. startups that identity or KYC, or auditing etc. Probably a lot of fintech.

How big can this thing get? We can't all be servicing the state? Someone has to grow the food, build the houses etc. (Although even these have their share of government sacrificial offering)
