The less you eat, drink and buy books; the less you go to the theatre, the dance hall, the public house; the less you think, love, theorise, sing, paint, fence, etc., the more you save – the greater becomes your treasure which neither moths nor rust will devour – your capital. The less you are, the less you express your own life, the more you have i.e., the greater is your alienated life, the greater is the store of your estranged being.

— Karl Marx, Human Requirements and Division of Labour Under the Rule of Private Property
