Why do people say Asians get surgery and lighten their skin to look Caucasian?

they are not trying to be white!!! iam full asian and i naturally have light skin. and i naturally have big bright eyes. people tell me they look like black pearls. and i love my jack black hair. and i know asian girls who are naturally like that. some white people don't like their eyes..some one told me blue eyes look scary. and people with light eye color tend to be weak(??). and so? lots of white girls get nose job and straigthen their hair..want higher cheeck bones, so does it mean they want to be white? and white people want full lips and they like getting tan, so does that mean they want to be black or latina???
