(pardon the napkin math) If you live in a town of, say, 25k people and your town has 10 garbage collectors (napkin math: each pair covers 1000 people's trash every weekday) each earning minimum wage 15k/year (if it takes 1min to pick up trash for an average household of 2, we get just over the standard 2k work-hour year. To me this sounds like fast operation and low house size. But the low end of the trash costs demonstrates the point), then each person in town is paying $6 to their garbage collectors. Even more considering benefits and non-labor costs. If healthcare, garbage truck maintenance and, I dunno, landfill fees (are those a thing?) cost the city a mere 100k/year, every person is paying $10 for garbage collection.
So in the napkin scenario, for each individual, garbage collectors are valued at 10x what Oprah is. And that's with all my napkin math assumptions choosing the lowest costs. Plausible scenarios could go as high as 100x individual value for garbage collection over Oprah mic talking. But Oprah can do her less-individually-important job for 1000x more people. It's an issue of reach.
