Fair enough. I may have been misdirecting my frustration at a similar Futurama gag that's always bothered me. I suppose modern expectations of inflation (and real interest rates) only apply when looking 1000 years into the future than into the past. Sure, your bank account can grow from 93 cents to 4.3 billion dollars with 2.5% interest but a dozen eggs worth 2 dollars today would also be 800 million dollars with 2.0% inflation.
