As I mentioned in another thread I disagree with you. Up until the first part of 1951 the Chinese were basically winning. They decimated the UN forces above the 38th parallel and pushed the UN forces back beyond Seoul and recaptured it. As a matter of fact contingency plans were drawn up to have the Navy evacuate all UN forces from Korea. The defeatist attitude was at the highest ebb in the US and Japan. The Chinese government felt that the UN forces were weak and ready to give up. This is were the Chinese made their mistake. General Ridgway was put in command of all UN forces in Korea and he believed he could stop the Chinese. He was going back to the 38th, then formulated a plan to fortify his lines and make the war too costly for the Chinese to continue. Remember, they had no artillery and what we call close air support. Yes they, the Chinese, had the best fighters in Korea until the F84E and F86 Saberjets were introduced which were more than a match for the MIG's. The Chinese spring offensive of 1951 is when they started losing the war and sustaining massive casualties as General Ridgway planed.
However, I agree that the Chinese, at that time, did not place the same value on people that Westerner's do and especially the US. The average US soldier, or marine will do almost anything not to leave anyone behind. However, it seems now that has changed among our political and military leaders....Benghazi comes to mind.
