Also, yes... there are skilled and unskilled labor jobs. I think we all have an understanding of what skilled and unskilled are. I think we commonly consider people in the medical profession, the trades and STEM to be "skilled" in the traditional sense.
I think the point that donjo is pointing out is an attribute that maybe shouldn't be called a "skill" sense that triggers a lot of people. It is a human trait revolving around ability to learn quickly, work ethic, showing up for work... whatever that trait is called, it is in high demand and in low supply... therefore, there should be more "value" placed on it. And I know that word "value" will also trigger people because they immediately assume that the argument is being made that the janitor should make as much as the CEO. Just saying that a lot of these workers are underappreciated and are underpaid.
I suppose the next thing people will swarm on now will be me saying "underpaid", which I think is one of the two issues that has been revealed in these two discussions.
Some of you people want to maintain control over these employees (meaning allowing businesses to do whatever they want with employees including an experimental jab mandate) and keep them underpaid (which is why so many got butthurt about the word "valuable").
