If I remember correctly, it was part of the research for the Polly Toynbee/David Walker book which produced some fascinating polling on what people thought the average wage was.
The more someone earned, the higher they believed the norm was. City types, rolling in their big salaries and even bigger bonuses, assumed that the average income was close on £100,000.
Perhaps it shouldn't come as too much of a surprise to learn that those on huge incomes have no idea how ordinary people live, especially ones on low wages. But I have come to the conclusion that the reverse is true, also.
Ordinary people - and I include the middle classes - don't really grasp how the very rich live.
Most of us don't know what we would do with a big Lottery win. So how can we imagine winning the Lottery every year. Year after year. Money for those who are on that gravy train is simply meaningless by the standards of the huddled masses.
How many homes do you need? Cars? Holidays? Servants?
Remember, these are mainly not people who grew up like that but the ones lucky enough to have taken a particular fork in the road when they started work. The fork which was signposted: This way to investment banking.
The British people are cross but they aren't so angry that they will take to the streets or absolutely demand that the Government stops the rabid bonus culture.
Is it because they have fallen for the coalition - and New Labour - nonsense that the billions poured in to save the banks was due to an international Act Of God. Or is that they just don't grasp how the bankers are taking the piss at our expense?
