But your comment is pretty clearly motivated by an ideological commitment to the rich having more and the poor having less, rather than some genuine concern with insufficient investment. Why not just be honest about it instead of hiding behind this ideological wordplay?
Labelling the freedom of choice of a low income worker to leave a job they hate and/or work a bit less as "deadweight loss" is reveals a lot. I suppose you think the lack of ten year old children working in coal mines is deadweight loss too.
