I agree that it was more common to have 'staff' about 50 years ago, but people didn't have washing machines, tumble driers, hoovers that worked properly, dish washers etc. etc.
The cost of buying a house has changed greatly. My parents live in the same area they moved into 30 years ago based on my dad's salary as a middle manager (the equivalent of maybe 40K now?). Now they would need to raise £700K to buy a similar house. However, we had one TV, one record player, one car and if we went abroad we went there on the ferry and camped. I certainly never flew with them or stayed in a hotel.
I can winge about "not being able to buy a house in the 'London' village where I grew up, ha, ha, ha,", but I think I have a more expensive lifestyle than they did in terms of travel and buying gadgets like ipods. Equally, I benefit from the increase in value of their house, whether that be by inheriting it or using its value to contribute to their care should they need it.
Meanwhile, I didn't get the impression that Rachel Johnstone had been forced to send her (I think 4?) children to gasp! a state school.
RJ needs to wake up and find out what it really means to be poor in Britain in 2007 and it has nothing to do with Waitrose.
