So, if no one cleaned your toilets, picked and cooked your food, removed your garbage, swept your streets, shoveled your snow, trimmed your lawns, dug your ditches, mopped hospital floors, cleaned your clothes--that's no matter because that work is not important, but sitting behind a desk is indispensable.
Of course, if the people behind the desks could plan a world wherein all people who work hard can live a decent life, then maybe sitting behind a desk would indeed be an important job.

Where on earth did you see me speaking of importance of work? A more productive worker creates more wealth, which provides for a higher standard of living. When we we all were cleaning toilets, we lived to the age of 45 on average, and did not have modern medicine or airplanes. The airplanes are created by people behind the desks and workers on the assembly line --- both have a greater level of education than those clean toilets.
You also misconstrue the economic notion of education: it also includes training for what is manual work.
