The Russian Empire in 1917, the German and the Austro-Hungarian in 1918, and the Ottoman in 1922 were all ended in WW1.
The correct answer is - the labor force is cheaper.
The living standard in Mexico is much lower than the one in the United States. In accordance to it, the wages are much lower as well, so the labor force is very cheap when compared with the labor force of the United States.
In order to increase their profit, lots of companies have moved and made facilities in Mexico, so for the same work, they are paying the workers much less, and all owners would prefer that the same job is done for lesser amount of money.
