Did anything good come out of the Great Depression?

About this book

"Look at the events that lead to the Wall Street Crash of October 1929 and the shockwaves that it sent around the world, leading to economic crisis and financial panic and plunging millions into unemployment, eviction from their homes and grinding poverty. Explore the legacy of the Great Depression internationally, both in terms of the bad things that came out of it, such as political ferment leading to the rise of fascism, and the good things, including the expansion of the welfare state and provision for those in need, technological innovation and the rise of the cinema industry."--Amazon website.
