Oh look, we went from a global conspiracy to delete Adam Smith to 'I vaguely recall that 55 years ago I think my dad couldn't find him in the economics book's index.' This Old-Man-Thinks-He-Remembers-a-Thing style of post is certainly a choice, but it says more about your memory than it does anything else. As for your arithmetic, you are still making the same fundamental error. You are conflating administrative overhead with the total cost of providing services. A family receiving healthcare, school lunches, and housing assistance is receiving the value of those services, even if the State doesn't hand them a stack of cash equivalent to a chemist's salary.
Given your issues with memory and comprehension of the topics you want to discuss, let me point out that there is a massive difference between a professor teaching a curriculum in a classroom and a professional political operative who tours campuses with a camera crew specifically to trap teenagers in "gotcha" moments for social media clout. One is education and the other is performance art for the "statist" think tanks you claim to despise while glorifying their actions. It is also quite a feat to invent a number like '4,000 authoritarian think tanks' while defending a man whose entire career is subsidized by those very organizations.
Finally, your dream about being taught economics by the owner of the local five and dime, coupled with your demonstrated failure to grasp high school level concepts, says far more about your own comprehension than it does about anything else. A general store owner understands a cash register and a ledger. Macroeconomics involves systemic infrastructure and national services. If you think the two are interchangeable, it explains why you find a 7% administrative cost so confusing.
