My first remarks only considered the years 1914-1922. Looking over a slightly longer term, to 1940. A massive economic adjust will still occur in the 1920s & 1930s. Areas of critical economic growth of the previous fifty years were matured and no longer the source of high growth/high return. Coal energy, railroads, early generation steam ships, & other steam technology for mechanical power. The industrial models of the 19th Century were on the verge of being replaced as large scale investment targets by new technologies. Whenever this occurs there is considerable economic dislocation as people fail to adjust to the new order and lose wealth.
This of course affects labor. Skilled and semi skilled agricultural labor becomes surplus & the trend was to move to the urban centers where they were instantly converted to unskilled low wealth labor. Britain and France were far along in this trend & had reached some equilibrium and ability to accommodate remaining migration to urban centers/jobs. Germany, other Central Europe nations, and the US did not hit the peak of this labor conversion until later in the 20th Century. Some demographics data places it in the 1920s for the US, and possibly Germany.
The fragmented & relatively inefficient banking model of the 19th Century was well past its expiration date. The US had adopted a similar model to the British centralized banking system, & other economies were moving in that direction. However banking was still too dominated by elderly men who were clinging to practice and investment strategies more appropriate to 1890 or 1860.
The Great War aggravated the conditions of the Great Depression, but did not cause it in any way. That particular train wreck was pretty much inevitable. precisely how it might play out ATL I'll not try to predict. Suffice to say that sometime between 1920 & 1940 there is going to be a period of 'economic voltility', and some extended years of low wages and general misery.
