tariffs, quotas and trade barriers discourage world trade and businesses. Who pays for these tariffs and quota limitations? Often these costs are passed on to the consumer. When a country is open to trading with foreign nations it increases its customer base. When foreign nations trade it helps stimulate business growth and create competition and innovation of products and services. Just like businesses, countries have vested interests in doing what is best for their respective countries. I believe that the host country needs to negotiate the terms of doing business with a company that wants to come in and sell their products/services but not to the extent that it will discourage foreign companies from doing so but also not be taken advantage of either. What do you think?
