This is a much better characterization of Jaron's position AFAICT. His notions on middle class are deeply rooted in an economic theory of wealth distribution which is what we have largely today. However it is clear that technology, and information products in particular, are changing the wealth distribution significantly. Combined with observations that corporations in tech share their wealth more widely and you get a community which is distinctly biased toward the 'wealthy' end of the curve with a smaller middle class. Jaron is concerned how that plays out economically.

He is focused on the economical repercussions of the new economic models that are changing wealth distribution.

Think of the South in the civil war in the US. They were grasping to understand how industrialization would bring more economic safety than slavery.
