Without management of an account like that, who is to say a bank will even be accruing that much interest in that time? Who is to say that value isn't wiped out by a currency change like the French New Franc or the Mexican New Peso? How could a bank even pay out on an account like that? Who ensures that bank even stays in business?
And what happens to operating capital, or is this a "rainy day fund"?
But to get even more out there, how do we believe that the Sith have $20 a week to spend back then? Inflation has that showing up as 23x its value only 100 years ago, today's $20 is 1913's $469.02 based on the Consumer Price Index, that same $20 1000 years ago could be perceived as a fortune all to itself. Ah for the heady days of living on Coruscant a millennium ago, when you could buy an airspeeder for $20.
Perhaps you'd be more excited if Disney got Alan Greenspan to act as a script consultant? Although the way things have been looking lately, they'd probably screw that up and get Ben Stein or Ben Bernanke instead.Now I can't wait for the new trilogy...
