In this whole world, there is nobody more generous than the miser—the man who could deplete the world’s resources but chooses not to. The only difference between miserliness and philanthropy is that the philanthropist serves a favored few while the miser spreads his largess far and wide.If you build a house and refuse to buy a house, the rest of the world is one house richer. If you earn a dollar and refuse to spend a dollar, the rest of the world is one dollar richer—because you produced a dollar’s worth of goods and didn’t consume them.Who exactly gets those goods? That depends on how you save. Put a dollar in the bank and you’ll bid down the interest rate by just enough so someone somewhere can afford an extra dollar’s worth of vacation or home improvement. Put a dollar in your mattress and (by effectively reducing the money supply) you’ll drive down prices by just enough so someone somewhere can have an extra dollar’s worth of coffee with his dinner. Scrooge, no doubt a canny investor, lent his money at interest. His less conventional namesake Scrooge McDuck filled a vault with dollar bills to roll around in. No matter. Ebenezer Scrooge lowered interest rates. Scrooge McDuck lowered prices. Each Scrooge enriched his neighbors as much as any Lord Mayor who invited the town in for a Christmas meal.Saving is philanthropy, and—because this is both the Christmas season and the season of tax reform—it’s worth mentioning that the tax system should recognize as much. If there’s a tax deduction for charitable giving, there should be a tax deduction for saving. What you earn and don’t spend is your contribution to the world, and it’s equally a contribution whether you give it away or squirrel it away.
