Money is funny!
In order to have it, you must have not spent it; you can not spend it for many years, but as soon as it is spent you no longer have it saved.
What is money good for anyway? Its only good for what you can spend it on!
Since dollar cash is based on whimsical government promises, the perverse incentive is that the longer you save the less it is worth!
Most of the paradoxes run and hide when you start talking about value instead of money, but who wants a world without paradoxes ;p
May the Lord's Abundance be ever with you, however much your money happens to be worth!
You can save money and then invest it, so that it generates more money. And if you have saved and invested enough, that its generated interest can be spent without spending the savings. Thus it would be possible to both spend the money, and still have it saved.
