You are technically correct, in the literal sense that managers and executives have work to do.

It should be noted, however, that it is the workers (not the company owners/investors) that create all the products that are up for sale and the infrastructure necessary to begin production (e.g., roads, bridges, electricity, education, etc.). Hence, when a CEO say that they "built" the company, they are obfuscating the exploitation of the labor of workers who transform raw materials into all the useful commodities we enjoy.
