Well, for starters, Elon Musk actively adheres to the Labor Theory of Value. He named it differently, with the "Idiot Index". Except, its an inverse LTV.

Both theories use the SAME formula.

Final Price = Raw Materials + Labor + Overhead + Profit

The difference is that Marx pushed that labor is what makes a thing have value. Wheres Musk pushes that humans have 0 value, and should be removed whereever possible.

Same thing, different conclusion.

And know what happens when we get "perfect idiot index" of 1.0? There are no workers, no money, and wealth is accmulated purely in the hands of the elite. Hell, even Ford saw this in tge early 1900's - who'd buy cars if nobody can afford them?
