Sorry Xenia, my attempt at wit very late at night. Poor in retrospect.
I was intrigued by your example, because it is a commonplace misconception that it has always been hard to buy a property, and that things are not much worse now than they have ever been.
See this link for more details on average house prices and income multiples.
Are houses more unaffordable than they used to be?
I would dispute the figures in your example. A few small refinements show just how much things have changed for a first time buyer.
At the time you bought, your house cost 2.76 times your joint incomes. I am guessing because it was 1983, that you must have been in your early twenties at the time. This would mean you were in pretty much your first jobs. A teacher's starting salary in Harrow would be about 21k. Let's assume two teachers bought their first place on a combined income of 42k, at the income ratio that you needed - 2.76. This would give them 116k to buy a house. That in fact leaves them 134k short - the shortfall is bigger than they can technically borrow. For this they wouldn't even get a flat in Harrow.
I think the point is that house prices going up actually profit very few people. Most people live in their houses and that is pretty much the end of it. As a nation we are pouring ever increasing amounts of our wages into spiralling prices, and you have to ask why? It is almost completely unproductive.
It prevents us from investing money into things that could actually make a difference to people's lives. It squeezes incomes at all levels, which is one thing if you are Rachel Johnson bemoaning the cost of private schools. It is another if you are someone working on the minimum wage.
I realise that this article sounds like entitlement. However, if it is so hard to achieve a 'middle class' lifestyle, ho hard is it to achieve your 'working class' lifestyle of 30 years ago? Well, it is harder as well, pushing many families into dependency on benefits/credits of various kinds.
So the questions we need to ask ourselves as a nation is "Why have we got ourselves into this situation?" and "At what point did we decide that people's aspirations to live as they would like become irrelevant?"
Why shouldn't someone on a 100k salary have a decent life? I would aspire to one if I earned that much. This isn't entitlement. In a country where the overall wealth is increasing all the time, where economic growth has been high for a decade, it's a desire on the part of the citizens of this country to see some return for the increasing treadmill that is, in part, destroying family life.
