I am sympathetic to your argument. I just would like to point out the irony that you want to break up companies to improve our global competitiveness. I seem to recall hearing in the late 90s and early 2000s a theme that the US really needed to let these companies combine so we could have large national players who would have the scale to compete globally with other nations' mega-corps. (Not so much in terms of FAANG tech perhaps, but certainly in banking and many other sectors.) I'm not sure if there is some definitive research on what corporate size truly helps global competitiveness (but I'd expect that, as you say, smaller competitors in larger numbers tend to be more competitive.) But even in China car industry as transitioning today, the natural evolution of such a system is towards a fewer larger competitors. Kind of related to the iron law of oligarchy perhaps, this phenomena? https://en.wikipedia.org/wiki/Iron_law_of_oligarchy https://en.wikipedia.org/wiki/Iron_law_of_oligarchy
