Ok I get it now. I think a natural reading of my statement is that the original post was claiming some cognitive bias, in which white color workers felt themselves to be inherently better than blue collar workers, vs my own view that white color workers on average are actually worth more in the market.

My claim is that there is no cognitive bias, but that white collar workers in general are worth more (because they possess a rarer set of skills).
