Let us take at the period from 1913-2006, where we have complete data. So what do they mean, when they say the dollar lost 95.1% of its value in those 93 years? Essentially, an average good/service that cost $1 in 2006, used to be priced at 4.9 cents in 1913. In other words, the average price level of goods/services increased by 1930% since 1913. True, but guess what, average earned income increased by 6560% during the same time period. Average earned income rose from $740/yr in 1913 to $49,300/yr in 2006. Adjusting for inflation, $740/yr in 1913 is $15,000/yr in 2006 dollars. Average incomes, not only kept pace, but beat price inflation by 230%.
So does it make any sense all to say the dollar lost value? In reality, the REAL purchasing power of the average American, has increased by 230% in the past century. Sure, prices were cheap in 1913, but $740/yr doesn't buy you a whole lot, not anymore than 15,000/yr today. Even this statistic doesn't fully capture the quality of life gains of the last century. A household making $15,000/yr today is well below the poverty line, but yet, they are highly likely to have a refrigerator, indoor plumbing, electricity, tv, cell phone and maybe even heating and cooling. They are highly likely to have government help in making ends meet - food stamps, subsidized housing, Medicaid etc:. And yeah, thanks to advances in medicine, they don't have to worry about half their children dying before the age of 5. Their analogue in 1913, making $740/yr had none of these "luxuries". And that was the average income... Can you imagine what the poverty line looked like then?
