What is the best argument for a negative response to this issue?

The Emerging Issues Event gives FBLA members an opportunity to demonstrate skills in researching and presenting an emerging business issue. This team event helps members learn research skills. Team participants develop speaking ability and poise through oral presentation.
The global economy has presented opportunities and challenges for increased trade. Businesses in the United States have a code of ethics or rules for honest and fair business practices. American companies outsource jobs to countries like India and China with large populations and lower wages than the United States. These countries also have large markets for products and services made in America. The home-building and agriculture industries count on illegal workers from Mexico.
Participants will be expected to research the topic prior to the presentation.
They must be prepared to present an affirmative or negative argument for the business practice.
