I've never said any such thing. Individual dollars have lost value; individual purchasing power has not lost value--it's increased substantially since the Federal Reserve was created.
Why are you so obsessed with the value of an individual dollar if that value doesn't meaningfully reflect the purchasing power people have?
You're going to have to explain the Honda thing to me. I visited several car web sites and couldn't find a price for a DX model in 2013; I'm going to use a
2.4 LX 4dr Sedan because it's the next lowest priced car common to 2003 and 2013. The MSRP of that car in 2003 was $19,200; the MSRP of that car in 2013 was $21,680. I get $21,680 - $19,200 = $2,480 more expensive in 2013. How did you get a 300% increase?
