The Colombian exchange had a huge impact on the movement of people around the world. It opened the gates to two new continents. The indigenous people saw an invasion by people from Europe at first, people from other race and culture. The Europeans later started to bring in Africans on these two continents as well. As the time was passing, more and more people, from more and more countries and continents wanted to migrate toward these parts of the world. As those societies became more open toward migration, there was an influx of multiple different European ethnic groups, multiple different African ethnic groups, and in lesser degree East Asian people as well. All that movement of different people, from different ethnic groups, races, cultures, created societies were people from all over the world live together, work together, prosper together.
As a result of economic growth during the 1950s, the percentage of Americans who were in the middle class "increased dramatically". This was due primarily to the fact that there were far more jobs available, since World War II had helped create them.
The economy is stimulated by giving money to consumers.
