Actually the story of the 1960s family with 5 kids, a car and a good house on a worker’s salary is from Britain:

• A journalist in The Guardian discovered that his university educated daughter's salary was the same salary inflation adjusted as his factory worker father's salary, yet wasn't enough for even a small appartment in London whilst hist father's salary paid for the above mentioned house, car and family of 5, so he wrote an article about it.

Mind you, we see some version of this in plenty of other countries in at least the West - the story of how two university educated people need to work full time in a white collar job now to afford what a single blue collar salary paid in the 1970s is pretty common, though the difference from peak to through isn't as large as in countries which were wealthier back in the 60s.

Even in my own native Portugal which was under a Fascist dictatorship until 74 and thus had no prosperous 60s in any way form or shape (in fact by then the country was so poor it was the recipient of Food Aid from the rest of Europe) and only really rose to normal European standards after the 74 Revolution, you see that effect between the 80s and present day - it now takes the salary of 2 university white collar workers to buy what my father's single blue collar worker salary bought in the 80s.

People's purchasing power is way down even though according to official inflation figures it's supposedly not.

Note that official inflation figures are used in calculating GDP, were they deflate the Raw/Nominal GDP to make the Real GDP (the official one) and the more the inflation the less the Official GDP - in other words, the less the official inflation the more politicians can claim to have "grown the GDP" - ever since polticians started harping in the Press all about the GDP grew under their government there has been a strong political motivation to understate inflation (which is probably why the official inflation figures don't include house price inflation).
