"Giving back to society" is a swell little notion but an entirely loaded one in our opinion for if you "give back", what exactly did you "take" in the first place?
Excellent video below that explores the morality of profits and conversely the immorality of subsidies that is exemplified (but not called out, specifically) in the rigged, crony capitalism of the Big Green sector of our nation's economy.
"We deal as equals by mutual consent to mutual advantage and I am proud of every penny that I have earned in this manner." - Hank Rearden, Atlas Shrugged
"When people enter into a voluntary transaction, they all expect to benefit but an involuntary transaction benefits some at the expense of others."
"Profits earned honestly in the market place are moral. They arise from morality and they reinforce morality. The search for profit through voluntary exchange teaches people to be civil."
It's not "giving back", it's simply being civil and generous with the profits one has made from an honest and beneficial-to-society business enterprise.
