Inflation - A Shocking Truth

Everyone is aware that it now cost 49 cents to mail a letter or
a bill.  Today I conducted some research to ascertain how
much mailing a letter a bill payment in 1940 would cost. 
I selected 1940 because that is the year of my birth.
The cost to mail a first class letter/payment in 1940 was a mere
three cents. 

I then consulted the world wide web and check out the
inflation calulator.  I learned that three cents in
1940 had the same buying power as fifty cents does today
so it appears the Postal Service is right on target in
charging .49 to mail a letter today.
