It seems everything makes sense.
When the economy booms, the world actually stops moving forward while everyone focuses on making quick moneys.
When the depression comes, it actually pushes personal finances into tow extremes. That is, the difference between the riches and poor is expanded (Gilded Age). Meanwhile, it forces people to find new way, or new technologies (auto for ending the 1873 long depression) to boost the economy. So, it's always money + technology + cheap labor to move the world forward.
