The gun play can make for more entertaining stories.
Maybe the writers of stories are trying to match the potential audience (white Americans).
Portraying a lone person makes the character seem more heroic—it fits into the American ideal of rugged individualism.
(this is not my answer i just got this from someone else)
Many european nations and america desired to expand their "spheres of influence" and control parts of China for their own 'empire', which enables the nations to get more resources and other 'exotic' things that they do not have in their native lands.
False.
In fact, some New Deal programs borrowed ideas from things already done in Europe. For instance, already in the late 19th century, Germany under the leadership of Otto von Bismarck passed the Health Insurance Bill (1883), the Accident Insurance Bill (1884), and the Old Age and Disability Insurance Bill (1889). Such reforms in Germany continued after Bismarck ended his service as chancellor, with the Workers Protection Act (1891).
Germany's Old Age and Disability Insurance Bill of 1889 provided a pattern and precedent for the United States' Social Security Act, signed into law in 1935.
