Actually I'm not sure that is correct, either, but this could also be a chance to slow down the math for those who aren't following it closely.50 years of inflation at 2%: 1*(1-2%)^50= .364
25 years of inflation at 4%: 1*(1-4%)^25= .360
If we have 50 years of inflation, 2% every year, I get:
1.02 ^ 50 = 2.69x increase from original price
So a $20 item, after 50 years, costs:
$20 x 2.69 = $53.17
Those $53.17 of future dollars is worth just $20 today:
$20 / $53.17 = 0.376
I'm I'm correct in that approach, it's because losing 2% per year is not the same as a 2% increase in prices:
1 / 1.02 = 0.9804
