The public disagreements are over things that the corporations absolutely don't care about one way or the other, or that they are divided over. The one thing neither side will ever even hint at doing is make corporations and their officers responsible for the consequences of their actions and choices.
I just want and concrete example.
To pretend to be unaware of dependence of most US politicians on corporate campaign donations is not a way to participate in an honest discussion.
For the phenomenon I am talking about, both sides agree, and you never hear a peep about what they agreed on. For example, was any corporate officer of any large bank prosecuted for millions of counts of fraud, after 2008? For even one count? Did any single one go to prison? Tim Geithner got made SecTreas, instead.
The DoD every year utterly fails to account for how most of the money they are handed was spent. Do you imagine that is because it can't be done? That they can't follow orders? The major corporations account for more than that amount, every year, every dime.
If you want to talk about the 2008 financial crisis, ok. Why did Dodd-Frank pass? Why did the corporate backers allow for the creation of the CFPB? How is it that only once Trump came into office did it stop doing its job?
You are asserting that there is a cabal of corporations controlling politics in the USA, what do they actually agree on specifically? Why have things in many instances actually changed when administrations change?
Things change because things change. Look to the things that don't change, instead. Spook whistleblowers are hounded into solitary confinement right through Bush, Obama, and Trump presidencies. Random innocent people are vaporized from the sky in countries we are not at war with, right through Bush, Obama, and Trump presidencies. Massive fraud campaigns ordered by officers of major corporations are prosecuted with exactly zero of such officers ever imprisoned or even inconvenienced, right through Bush, Obama, and Trump presidencies.
