Yes physical beauty is not important but in this practical world everything is materialistic. White or fair skin attracts the people as compared to dark skin and it is probably natural human tendency..
I think the skin is different area wise and no one can help that. I am from Punjab where skin is little fairer but that does not mean that we should not accept people from other states. May be some people think that way but now the things are changing and people looking for brain.
Yes thats true people are looking for brain and money too. Now a days people get married if the opposite person is well earner and well educated.
A girl will look for a guy who earn very well and guy looks for a girl who is earning well too and settled at her work.
