20% of the us economy is manufacturing and another 30% is anciliary activities related to manufacturing like transportation and retail and mining, which are just other steps in the supply chain (you cant make products unless they get transported and sold in a shop). another 10% is construction which counts as "making things" in this case, buildings. the rest of the service industries still make real things and services which you still need, like restaurants or movies and tv shows. the parts of the economy you would consider to be parasitic like banking are only 10% and colleges and hospitals that overcharge. its like a quarter of the economy, the other 75% is real and 50% is direct manufacture or related to manufacture you cant have an economy that is 100% manufacture of diesel trucks, where you are born in a diesel truck factory and eat diesel trucks and go to school in a diesel trucks and get lectured by a diesel truck and then go to sleep in a diesel truck
