This question is inspired from the current demonetization that is happening.
I remember that Patanjali Yoga Sutras talk about Aparigraha which means non-accumulation. This refers to non-accumulation of thoughts and emotions i.e. not holding onto things and letting go. Also, in the physical realm, it refers to non-accumulation of unnecessary resources including wealth. The benefit of Aparigraha is said to be that the knowledge of other people and past lives come to you.
Which other scriptures talk about hoarding of wealth and resources?
