All the money in each country went towards the war instead of going towards trading with other countries. Due to the war being such a big cost, it caused the countries to put most of their money into the thing they thought was most important which was the war, causing the money that was usually put into trade was now put into the war causing the world trade to be disrupted.
This changed the world because we stopped trading with other countries. This means that the trade we normally get from other countries was stopped forcing us to use the things we make here in the united states.
Huge debts
Due to all the money put into the war, at the end of the war many countries were left in economic ruins. The United States of America, who had been in an economic boom with factories being unaffected by the war and performing better than ever, pumping out war materials that went out to other countries changed after the war ended due to countries no longer needing these war materials. Germany, after the war was in a major economic trouble, after being forced to pay heavy reparations leading to their economy basically becoming worthless. France and Britain were also affected negatively by the war due to its extremely high cost of it however, they were able to recover from it.
This changed the war because many of the countries who were in the war were not used to being in this much debt and in this bad of an economy that their new way of life after the war was a dramatic change. Due to the lack of money in each country there was no longer the ability to buy things you wanted, you had to live on a budget purchasing only the things you truly needed. This changed the world because many countries were in so much debt that it had taken years to pay off and get their economy back in a good place.
Massive unemployment
Due to the huge expense that all the countries spent towards their war efforts they were left with huge amounts of debt causing countries to have to cut down how they spent their money. Many countries had to cut down on the amount of workers they had because they hardly had enough money to pay the workers they really needed. Many workers were so furious because of the low wages and awful conditions they were getting that nearly 2.4 million workers went on strike.
This affected the world because now that there was not money to be able to pay all of these workers many people were left without jobs which caused a domino effect. This means that because most people did not have jobs, or if they did they had very low wages which meant they did not have money to spend on things that they did not need. Due to people not needing these things it affected the companies who were not making enough money therefore letting go of more workers. This greatly affect the economy in all countries that were involved in the war.
