The Mars Bar comparison
MIKIP, re the "value" of the 1939 RAF to that of today try using the Mars Bar method of comparison; take the cost of a 1939 Mars Bar (first marketed in the UK 1932) and divide that cost into the cost of RAF at that date. Do the same with today's Mars Bar and the present RAF. Then see which gives you most bars! It may seem a little silly but economists use this method of historical comparison all the time and its surprisingly accurate! An alternative view-point could of course be that with economists thinking about chocolate its no wonder the world economy is in the state it is!!!!
