I do not think that the crisis is going to go on long enough to effect any major change in people's attitudes. Even a world war did not make that much difference, in fact, quite the opposite, it sent people back to re creating their rose tinted picture of what the world was like before the war, women in the home, men out at work
The first small seeds of change did not show until the mid 50s and didn't really blossom until the 1960s, some 20 years after the war ended.
I do not think it is the budgeting or managing on a small income that is causing problems, but the fact that we no longer build our lives around our home. Now we are always going out of our houses, to shop, to eat, to enjoy leisure facilities, even of it is just a drive out to, and walk round a local place of beauty or interest. Modern houses and flats are about half the size of their equivalents built70 years ago and as for gardens. The back garden of most new houses are no bigger than the back yards of the Victorian slum housing, now mainly demolished.
