Great video! I wonder what percentage of monthly household income an average book cost then as opposed to now.
Cost of books in 1947? $0.25 to $2.50 http://commons.wikimedia.org/wiki/File:AmericasBestComics220...
$1.50 / $3,000 = 0.05% of income in 1947 $7.99 / $49,777 (2009) = 0.016% of income in 2009
Some other costs in 1947: Average Cost of new house $6,600.00 Average wages per year $2,850.00 Cost of a gallon of Gas 15 cents Average Cost of a new car $1,300.00 Loaf of Bread 13 cents United States Postage Stamp 3 cents Men's Sweater $8.50 Bulova Men's Watch $52.50 from http://www.thepeoplehistory.com/1947.html
