How should a nation-state develop its foreign policy in accordance to iits values and in connection to the development of its domestic policy?

A nation, if I am to understand our assignment, develops its domestic policy in accordance with the majority value of the people. From this point the nation then devotes it’s time to working with other nations that help support and sustain its values, and improves its standard of living. In a perfect situation a nation that engages foreign policy with another nation, will give as much as it receives, improving the quality of life for the other nation as well. In the case of the United States, this is very rarely the case. According to our text, The United States is only concerned with making money and it seems that the way to make money is investing overseas, from lower wages, to loaning foreign governments money. How does taking jobs from Americans and bailing other countries out of debt, help America? Some countries we have bullied our way into and others we take more than we give. The way that we are investing is by carrying a bigger stick.
The other countries of the world are sending us far more than we are sending them. Now it is almost to the point that we are becoming dependent on other countries. We are one of the most advanced, resource rich countries in the world. We have a huge military pointed at every ocean and every continent in the world. Yet we still have millions without proper healthcare or even enough food to eat. A nation is supposed to take care of itself first and yet we are floundering like a fish out of water. Perhaps we need to stop looking at our foreign policy and look domestically instead.
