Uh I think you confuse the € and the Francs there ... no ???
In 1983, I think that in Strasbourg, an apartment of 80m² sold for 100-150 francs ... and not 000 €, therefore 80700 francs ...
My parents started working at less than 1000 francs / month in the 70s ...
I say that "by feeling" ... but please give us the sources of the figures that you put forward ...
ps: in the 80s the rate of mortgage was at 7 to 8% and mortgage was made over 15 years max ... 10 years on average! Since 2010, it may be only 4% / year but it is 30 years or 40 years of credit ... which is winning in history in your opinion ???
