For those thinking that we need to ignore/step over mid 20th century ideas; consider the following:
In 1816 at the conferenceof Vienna, the fastest way to reliably send messages or travel was a galloping horse, as it had been since the dawn of time. Railways barely existed, Food preservation was by the old methods of salting and smoking, or the recently discovered canning process that was unreliable at best.
Refrigeration was known about but not practically usable.
100 years later at the Somme; the following technologies were used to destroy Europe; automotive trucks
Trains, aviation, refrigerator rail cars, canned food, mass production of bullets, shells and all known weapons and rapid telecommunications via telephone and telegraph.
Musolini was born in 1883, Hitler in 1889.
The world had changed more completely from 1820 to 1920 than all of human history to 1820.
Our political, governmental, economic, familial, religious, academic and social structures are still playing catch up to the massive technological changes of the 19th-21st centuries.
Fascism, National Socialism, and all other related ideologies are the only realistic attempt to grapple with those profound changes
