The things we create today enable many more people to create things tomorrow. Building things without consuming anything for yourself leaves real valuable goods available to productive uses that serve others. As the total amount of wealth grows in relation to the total supply of money, the share of what you have earned (without spending it) buys you more. A fixed money supply helps to discourage mindless consunption & encourage extremely efficient use of all available resources. There is a reward of greater purchasing power for all who live frugally.
