This is only an issue if you're treating the dollar as a long-term investment. After all, we're talking about a timespan of 101 years here.
Nobody has their retirement money or investment money in savings accounts. If they have them in government backed securities at all they'll be in treasury bills, whose returns have greatly exceeded inflation. $10,000 invested in a 10-year treasury fund 10 years ago would be worth $17,000 today.
