There are important differences in the nature of the declines. The current series looks like a bear market in the form of 1973-4 whereas 1929-32 was much more precipitous.

"Repentance and forgiveness are the two great gifts of God. But there is the third and greatest gift of all, which is thankfulness. For with thankfulness our sinful pride is vanquished, our hearts are opened, and love enters — and a light comes into our life."
Jesse, Love and Thankfulness, 15 November 2018
