Now factor price and wage inflation over that period and, in terms of relative purchasing power, you still took a 50% hit against purchase price. It's exactly the same thing you hear on those popular antique valuation television programs. An item is valued at say £500 and the punter states that their grandparent paid £30 for it in 1935. The expert says didn't they do well as its value has increased by £470. Ignores the fact that the purchasing power of £30 in 1935 was greater than £500 in 2014.
