err..... dont want to put a downer on anything but WW2 and VE day were not in the 1930's. I have a thing for 1930's decor etc. and buying "antiques" from the time.
1930's - The Depression ( although unemployment was high in Britian in the 1920's, it eased somewhat circa 1933). Abdication of King Edward VIII,which have been mentioned.
Art Deco was the big thing.
Fashion changed. Could look at informality movement.
Education expanded. School leaving was raised to 14. Working class went to ElementarySchools,Middle class to Grammars and Upper Class to Public Schools but there wasthe " scholarship" ( most counties had one) for the clever working class boy.
Icecreams and chocolate firmsexpanded ( look at some of the old names and choccies that are still around - Kit Kat, Milky Way, Rolo, Smarties etc.) Jaffa Cakes, Twigglets and Blue Ribband made an appearance around then tooas did Penguins.
TV, talking films ( The Jazz Singer was 1927) . Most people had a radio in the 1930's.
Poverty ( which could be compared to todays). The rise of the Black Shirts ( comparative movements across all countries). Chamberlain, appeasement.
Slum housing.
Compared to a construction boom and new houses for the middle classes. Home ownership - 27% owned their own homes in the 1930's. But therewas alos " Rackman" ( by word for rip off land lords)
The expansion of the " grid Iron" ( electricity) which came to most ordinary people in the 1930's.
Rise of cars in the more general population (my granddad had a car and he was no middle class man,but a more secure skilled worker).
Maybe contrast between the haves and the have nots?
It was the " long weekend between the wars" - and was quite prosperous and forward looking for many. The War to end all wars had been done they thought and it was supposed to be a time of making Britian a country fit for Heroes - and it went badly wrong with the depression..... but it still was a good time for around 80% of the population. .
Books - Cold Comfort Farm? Most Agatha Christie. The genre of the time was cowboys and crime stories mostly. Thats what people read - maybe you could look at that?
