Yes, yes, yes. We've heard this before. For some X, the top X% of society by skill/productivity/motivation will always be able to find remunerative work.
The question is: what's the value of X? For some fields it has always been very small, like in philosophy.
However, our entire notion of "democratic capitalism" has always depended on the notion that over all fields and the entire population taken as a whole, the value of X would be a fairly large majority. There has always been some notion that the bottom Y%, where Y = 100-X, will inevitably have trouble finding jobs, but nobody outside the radical Left has ever really faced up to the notion that at some point Y might range between 20%-50%.
