Why are so many groups opposed to free global trade?
Because "free global trade" is seldom truly "free". Many nations
will subsidize their goods and services to force the price down in
foreign markets. That gives them an advantage, changing the value
of their money and often causing financial destabilization in other
industrialized nations. Other nations deliberately create a
national sense of pride that results in a willingness to pay more
for their products even though foreign goods or services might be
better. Japan is a good example. They would rather pay several
dollars for a Japanese melon rather than purchase a foreign melon
for much less money even if the quality is the same.
