I refer you to my post above. This is why we need to educate children about the reality of the 20th century.
Housing wasn't' run down' - it was terrible for working people , 2 up 2 down hovels and back to backs, particularly near ports and factories where the poor lived, terrible over crowding made worse by huge tracts of housing being bombed in virtually all cities and ports. Whole families living in cellars or worse.
Many people's work was insecure so they couldn't possibly get a mortgage and buy a house. It was often extremely difficult for men ( and even more so for women) to get jobs. Understandably many men especially needed time to recover from the trauma of War or were exhausted by 12 hour shifts in factories followed by further hours unpaid as firemen etc. The pressure to increase output yet again was continuous.
Between September 1939 until Russia entered the War in 1941 Britain stood alone, horrified, terrified and watching the advance of the Fascist German armies across Europe In Czechoslovakia, the Netherlands, Belgium, Poland, Russia etc. It wasn't until the defeat of the Germans and their Allies by the Russians at Stalingrad in 1943 that people been to believe that there was hope.
The poorer sections of society, almost all working class people, definitely couldn't buy a house on one wage or two! They didn't have savings for a deposit. This was why the postwar aim was to build council houses at a low rent.
The vast majority of working class families were not going on holiday but maybe affording a day trip to Blackpool etc. if they were in a skilled job.
The political agitation in the Forces and the determination by the returning troops etc that they were not going to be betrayed like the soldiers of the First World War were, lead to the defeat of the Conservatives and Churchill in the 1945 General Election and the Welfare State of the Labour Atlee Government ( NHS, legal aid etc. ) 'to fight disease, squalor, want, ignorance, idleness'.
Thousands of men came into the workforce from the forces post 1945, maybe having been recruited at only 18 + and having their lives disrupted for 5 years and came out traumatised at what they had suffered and seen. They were the lucky ones who didn't die. ( Dirk Bogarde said he never recovered from the horror of seeing the inmates of the Concentration Camp he helped liberate ). Many soldiers had been tortured and starved in Japan
The children born before or during the War were taken from their families , sometimes as babies or toddlers and taken to live with people who were forced to take them in but might have been less than pleased. Some were cruelly exploited.
(And we had it much better that the people of Europe who suffered from starvation, massacres from vicious, invading armies etc.etc.) The 'boomers' of the 40, 50 etc didn't just have to cope with rationing of food, lack of goods in shops etc.( which was stressful for the whole family ) but the traumatising psychological aftermath of a cruel war.
