Genuinely want to know if this is in the realm of or has been proven scientifically.

I find the following interesting:
Nationalsocialism was a massive success and brought society out of extreme depression and general decay (massive suicide rates and degeneracy during the Weinmar Republic) and dramatically reduced unemployment, and caused the economy, and the progress of technology and science, and the well-being of the citizens to absolutely skyrocket up to new heights, all in less than 1 year. No miracle like this has ever been witnessed before or since.

Please note: I'm not interested in personal opinions. Keep it strictly scientific please.
