“You mean like the Big 3 automakers?”
Nope, you have to go further back than the last 100 years of corruption.
Okay, please give me some examples of this magical time where corporations came together for specific reasons and put the best interests of society above the profits their companies were expected to generate. Heck if companies get together like that, I'd mostly be afraid they were colluding to fix prices. Corporations very reason for existing is to make money, not tackle social ills. They are not jobs programs, they are created to make money.
