There is no such thing as unskilled labor. I promise you, without training, you would fail miserably when asked to crank out big macs all day for a living. Just like you would if you were tasked for any other “unskilled labor” that you haven’t been trained to do. That means there is skill to it.
Unskilled labor is a myth created to justify paying human beings less than a living wage to line rich men’s pockets.
