How did World War 1 affect families?

When the war started factories started making more war materials and that meant the factories had to hire more people to do all the work to make the materials. When the United states entered the war in 1917 the economy in the whole country went up. When the war ended though people lost their jobs and the economy in the country went down dramaticly. The factories that were making guns during the war were now making type writters and factories that were making bullets were now making something totally different. Since the factorise didnt need as much supplys the workers that were making guns and stuff for the war got laid off because the supply of the guns and other war materials, the people didnt have to make as many of those. also i am EXTREMILY old and i have no kids im writing this.
