Entirely agree with you, but I also lend some credence to the worry that capital owners and the managerial class might not want to pay a six-figure salary for "knowing the questions to ask".
However, the first part applies to programmers, too. A lot of the value of code _was_ simply in the fact that it was written, so you don't have to write it yourself. I'm not suggesting there isn't more to the value proposition, but the value destruction is there.
