When I think of the word liberation I think of freedom. Liberty is a basic right every American should have.
They just do it trust me.
I would say true because this was the time of "boom", as we called it.
A lot of mass production and all that ( More making cars, food, and lots more )
After that, however, was around the Great Depression, when lot's of things and people were lost.
Glad I could help, and good luck!
