For example, we bought a company, and over the next year or so doubled wages in that company. Our "social responsibility" in that case was to spend shareholder money so that workers had a living wage. That doesn't seem to be the story I hear about say Amazon.

Yes, we've also spent money outside of those 3 groups. We contribute to charity. We spend money encouraging staff (and customers) to get cancer screenings etc. We spend (I guess shareholder money) on lots of things that are adjacent to our actual business.

Frankly, in the long run, I think it ultimately helps the business. It makes us "human" and reminds us that we control money, the money does not control us. This permeates through employee relationships, it permeates customer relationships. Ultimately that makes for a stronger company, built to last.

We've had acquisition offers. The shareholders have resisted them so far (despite easy riches) because we've seen what happens to other companies our size when they get acquired. Shareholder interest flows up. Staff (and by extension society) interest goes down. Ultimately most everyone leaves.
