Equality is what we should all stand for

I seriously think the United Nations has to do something to equality. I personally think a citizen of America is equal to a citizen of China. I mean we should be all equal irrespective of what Nationality we come from. I also think the same law should apply to everyone of us no matter where we find ourselves. So I don’t see the reason why some people will be considered as the “Citizen of the World” If I need a visa to enter a country then  everyone should be also asked to present a visa to enter the same country that way nobody feels they are superior  to anyone. I seriously think Equal Right should be given to all. What do you all think?
