About Government Manipulation

I am staying with an American family for Christmas this year. I am from China, so this is my first authentic Christmas. during the holiday, we opened gifts under the Christmas tree; we had socks full of Santa's presents; we had traditional American supper. All in all, I have been treated as family. Family members were: John, the father; Anna, the mother; Lily, the daughter; Georgie, the dog.

Yesterday before breakfast, I skyped with my parents who are in China now. They were happy to see me. They could not speak English, and the American family does not speak Chinese. My parents wanted to meet my American friends, and the American family wanted to say hi to my parents. I acted as the interpretor. When they saw each other, they were so excited. My parents waved and waved; Anna was asking me to translate how great it was to have me for Christmas; Anna was busy carrying Georgie; John was amazed at how my parents were wide awake since it was 11pm in China. Even though there was nothing much to say, I felt the friendliness and genuine curiosity people had towards other individuals floating in the air. 

Humans are all so nice and pure. Why cannot the government be like that? Chinese government manipulates the media to portray Americans as greedy and nosy; the American government pictured Chinese cheap and threatening. What's wrong with the whole system humans have worked out?  

Why cannot all the countries, all the people unite, and fight together against poverty, disease, natural disasters? What would it be like if there are no borders and division of countries? Humans are too self-seeking to benefit others even though he/she himself/herself could be benefited.
