I didn't read the objection as being that this company doesn't do enough for the common good of humanity, I read it as, this company doesn't have a large potential market.

Is it possible for any investment arm to invest in endeavours to uplift humanity?

Yup. Right now there is a rush to invest in African loan apps that have finally found ways to scalably extend credit to poor people in African countries. Hits a sweet spot between doing good and making business sense. There are also big investments in Africa into IOT companies that enable hire purchase for solar-powered home devices. Same sweet spot

Yes, you might read about Socially Responsible Investing.

Also, you can always contribute to charitable organizations. It's not an investment in the traditional sense, but changing the world to be 0.01% nicer is still a good investment.
