Purchasing power is required in order for someone to spend money.
Purchasing power means that someone has the ability to purchase
something (a product or service). Having confidence is not enough to
allow you to purchase something. You can't walk into a store with no
money or goods to barter and walk out with the product or service. Less
disposable income is more likely to lead to less purchasing power. In
order to purchase something, you need to give up something in order to
get what you want, generally you give up money. If you don't have
something you can easily give up, like money, you have less disposable
income.
