I would have to say during the industrial revolution. Many new inventions were being made and America started taxing goods being shipped to other countries. To remove taxes from certain countries, they moved factories to other countries so avoid Tariffs. It wasn't the colonization of America because America wasn't a country yet. It wasn't the reconstruction or world war 2 because the factories were already there from the industrial revolution.
Hope I helped!
The cause of unemployment in many countries is competition in the labor market. There are few employment opportunities. It leads to a situation where every available opportunity, there are more than one qualified individual. The effect is that it causes social and economic effects. The poverty index among the unemployed is high since some people do not have a source of income.
Hope this helps. :)
