Is Ethics and Etiquette the key to prosperity?

I believe one of the reasons why China could be a new economic world power in today's economy is because of their ethics and etiquettes (even though I don't agree with Chinese politics). In their country's politics, they have a form of respect and communication which allows them to talk about anything at which doesn't affects them personally. Japan has this as well which obviously allows them to speak freely of new ideas and solutions. This enables everyone to coexist harmoniously and collaborate in reforming what needs to be reformed and changing what needs to be changed (and not for the sake of benefiting others but the country as a whole).  In addition, I believe it’s important to introduce new ideas without ridicule and have the ability to state the facts and say what’s truthful without any backlash or slander from another. Part of what I want to accomplish in the United States is to create its own set of ethics and etiquettes in which society, government, and even the average individual can coexist in a harmonious way without judgment, prejudices, ridicule, inflicting harm towards others, or negative reaction to truths. I believe this will be the greatest tool which will lead the country to prosperity, innovation, and virtue. I believe if the country doesn’t look into this now or soon (along with the ability to reform or fix itself), it may indeed lose its position as a world power to China or another country.
