1) Hoarding money by individuals with large fortunes can lead to a fall in incomes and widespread unemployment as it withdraws money from economic circulation.
2) When money is hoarded and becomes scarce, economic exchange decreases and the economy grinds to a halt. As people's incomes decline due to decreased spending, unemployment and economic decline result.
3) Saving does not have the same negative impact as hoarding because saved money is accumulated for a purpose and will re-enter circulation when spent, whereas hoarded money is taken from the market without purpose.
