First of all, mass migration driving down wages offered. Immigrants ready to work longer hours and for less money. The USA has the highest total number of immigrants. For example some immigrants from Mexico came to America to find a more paid job. In Mexico, the outflow of workers reduces job competition and the level of wages increases. However, Mexican entrepreneurs are losing money, because their costs for paying wages to workers should be raised. On the other hand, in the USA  grows a job competition in the labor market that leads to a rise in wages, as a result of which American workers suffer losses. On the contrary, entrepreneurs in the United States, have more workers who are ready to earn less than American workers.
