I don't think anyone talked about the 'Great Depression' in 1930.

Instead, what we know call the 'Long Depression https://en.wikipedia.org/wiki/Long_Depression was often called the 'Great Depression' before that one took over the name.

Also keep in mind that the Great Depression was mostly a US thing. Many other countries had less incompetent policy in that time.
