The greed of gain has no time or limit to its capaciousness. Its one object is to produce and consume. It has pity neither for beautiful nature nor for living human beings. It is ruthlessly ready without a moment's hesitation to crush beauty and life out of them, molding them into money.
-Rabindranath Tagore (1861–1941)
This Quote helps illustrate the "ruthless" nature of consumerism, and greed in general. When money is involved, so much can go wrong. Marriages are broken, friends are lost, lives are destroyed, all for the pursuit of wealth. Although money isn't a bad thing in and of itself, it can build upon sore emotions and cause things like consumerism, buying things for the sake of buying, and one-upping the Joneses.
