Oxfam, mostly known from the inequality reports like "Eight men own the same wealth as the poorest half of the world", have published this paper with analysis of the causes of inequality. Very similar to your analysis. Also covering "The false assumptions driving the economy of the 1%" and "A human economy designed for the 99%". Unusual clear analysis pointing to the richest people/corporations and their anti-social ideology and use of power to maximizing their profits at the expense of the welfare for everybody else.
