The value of the dollar over time is largely meaningless unless you are a dollar investor (i.e. sit on lots of cash in consumer tier bank accounts). Generally once you have enough cash that this would meaningfully impact you, you are already beyond sitting on cash.

At the end of the day, the dollar or any other currency, is just a conversion tool for [value created] to [goods/services received]. A ratio of 3/1 is equivalent to a ratio of 300/100, even if 3 and 1 are 99% smaller than 300 and 100. The numerator and denominator can move out of sync, creating periods of strain and arbitrage while they equilibrate, but what really matters is how much xyz you get per hour of work at job abc. And overwhelmingly we are leagues beyond 1914 in that regard.
