Economic prosperity in the 1950s and 60s meant that the newer generation could easily have settled lives and more wealth.
Explanation:
The post war generation grew up in an increasingly prosperous environment with a booming economy and willingness to settle with immovable property as they had quite a lot of wealth to spare.
More and more families began to have more free time and the rise of entertainment industry followed.
This was also followed by a high level of consumerism as the people had more money to spare so they started buying things from the money including stuff for their immovable assets.
