The cautionary tale here is that the Left had the House and Senate in 1974 and the author of that piece Bradford Snell (talk about a name that was on the nose) was a staffer for the Congressional committee trying to break up monopolies. He was a GM hater for a variety of reasons. Not saying if those reasons were valid or not.
Not having a majority anywhere in the US Government makes the opposition pretty damn weak. Not having any the media report on what is happening in a straight way is weaker.
GM surviving its bankruptcy in the 2000s probably had that guy rolling in his grave(not sure if he's alive or not).
This article takes on the thesis that the multi-nationals were as blamable as Snell and the other New Left types thought.

Let me state that the conditions on the ground are very different because in this case the monopoly is dominated by a person in Musk who has extra-Constitutional access and control of multiple US Government agencies and the executive branch and who is manipulating ongoing US foreign policy to punish allies (e.g., Poland).
The closest parallel to the WWII era might have been Henry Ford who was an anti-Semite but during WWII was nothing but patriotic and supplied several B-24s, Jeeps, M4 tanks, etc. Actually, Ford empowered and on drugs might have been very similar but even he didn't control as much monopolistic power as Musk does.
