I disagree. Without Frtiz Haber inventing nitrogen fertilizer there wouldn't even be people to do unskilled labor.

This class battle has to stop. All economic fields are productive given that the market is valuing it. What's not productive is corruption and hoarding and middle manager fiddling. We have science to determine all that so we don't even need to gut feel this out.

Someone researching "transgender mice" can low key add more value than thousands or millions of "unskilled laborers". We need to diversify and value all avenues of our collective production and growth because thats just a smart thing to do. Except for billionaires and hoarders which clearly are a net negative.

Putting skills in the right place does help. Your postdoc in agricultural sustainability will help all the "unskilled" agricultural labourers. Without you, they produce less in the long run. But without them, you get nothing at all.
