Today's over the top use of the phrase give back annoys me. It implies a certain world view typically related to those ideologies of the left. It assumes that the successful in this world somehow owe their success to the unsuccessful; that the wealthy owe the poor for their wealth; that the educated owe the ignorant for their knowledge; that the free in one society somehow owe the oppressed in another.
Disagreeing with this concept or even just questioning its validity or propriety can quickly bring down the wrath of the shrieking drone-class of the default left who often lack the intellectual depth to discuss the topic any further than the periphery. I prefer to use words like charity, generosity, donation, or even the more modern gifting.
