While I see your point that all labor has value, skills can be significantly more or less involved to learn and master. There are labor jobs that require certification or ongoing licensure to perform and those that do not. There are roles that involve the health and safety of others and those that do not.
I think the skills involved between fast food and warehouse packing are probably pretty comparable overall, but a blanket statement of “all labor is equal” really doesn’t hold true.
I bought one $60+ game that I absolutely hated after 20 minutes. I don’t plan on making that mistake again, just anecdotally supporting this theory.
