Answer:
Sometimes it is difficult to understand that what Americans consider a normal life is nothing but normal, not even by the standards of many European countries. The belief that everyone is equal under the law is held by a very small number of countries and most of them are located in North and South America, Australia and parts of Europe. The rest of the world is full with countries where its citizens are not always equal. E.g. social castes in India, countries that are not democratic, or even countries were royalty still exists.
Globalization, political and economic change are part of global change that hopefully will make everyone equal. As people can access information freely, they start to realize that they can also fight for their rights. When ideological barriers fall, trade barriers will also start to fall. Globalization is something that cannot be stopped and as more people realize that, the more globalization will spread.
