Yeah, that's what my parents thought, too. So, would a good thesis statement be something like: "I think that sweatshop labor, while it has some drawbacks, can be used to change a poorer nation into a wealthy one."
If we’d export liberalism, we would be working on equal footing with the rest of the world.
Set their nations’ wages at a minimum of $7/hour.
I would be careful with that second part there. You may want to suggest that it provides opportunities for individuals in developing nations to create wealth for their households and improve their material standard of living. Also, be careful with the phrase "sweatshop labor." It's rather charged, has a negative connotation, and is tough to defend. You could, however, argue that an employer ought not to adopt a one-size-fits-all policy with regards to treatment of employees in different jurisdictions but ought to pay the prevailing market wage in any given country.
