If you are interested in how businesses work, then you should be interested in how corporations work (no, that's not redundant).
On the subject of how corporations work, I have read several articles about Senator Warren’s proposed Accountable Capitalism Act. I think the best commentary I have read is the series by Professor Bainbridge, in which he explains several measures by which this proposed legislation would (1) radically change, and (2) profoundly harm, large American corporations. Highly recommended.
The contents of this blog, this web site, and any writings by me that are linked here, are all my personal commentary. None of it is intended to be legal advice for your situation.
