I think the author 100% knew what he was doing by not mentioning QE directly at any point. It isn't just since 2008, the cut in 03-04 to 1% was basically why synthetic CDOs were invented...it is amazing that this happened twenty years ago, and there is still a "debate" about the long-term financial consequences of very low interest rates/QE.

Also, the issue with corporate taxes has been more to do with European tax havens. Places like Netherlands, Ireland, Luxembourg got very aggressive in offering corporations bilateral deals (i.e. bespoke deals on corporation tax outside the legal framework that applied to domestic companies). The US tax rate in the early 2010s was still 35%, it was only when revenue began moving offshore that the US felt the need to cut (not just the US, the same thing happened in the UK). The global minimum corporation tax deal is supposed to tackle this but, to be honest, the US should have cracked down on individual countries far sooner.
