Free trade is the practice of removing restrictions on imports and exports between countries. Such restrictions can include bans, quotas and taxes among other measures. The inclusion of countries such as Peru and Vietnam will see well-paying jobs exported to low-wage economies where workers have less protection from exploitation. It could do more harm to the domestic economy
Part of the TPP agreement would force control of seed banks, therefore controlling access to food. If you control the food sources you control the population. If you control the sustenance of the population you can force them into whatever form of compliance you wish. Sounds very communistic to me.
Free trade, while good in theory, harms the United States economy because it allows businesses to offshore their manufacturing operations to countries who do not have minimum wages. Workers in China can be paid a fraction of what American workers can be paid, and as a result bring manufacturing production costs down. If tariffs were in place on these foreign-made products, companies would not have an incentive to offshore their business.
Free trade agreements do not harm the domestic economy. Free trade among nations actually promotes economic growth for everyone; leading to a higher standard of living around the world. These trade agreements help consumers purchase products that are more affordable. Consumers can then have additional money to spend in the domestic economy on purchases that they would otherwise not have been able to afford. In short, the Democratic Party would be wrong to reject the TPP trade agreement, because free trade helps the domestic economy.
