What is 主流社会?

Some Chinese Americans often speak of  融入主流社会.  What is 主流社会 in America?  To be honest, I really don’t know for sure and I have never asked this question until this morning.  If we are doing pretty well with a comfortable house, nice cars, and decent and stable income, and most of all with your lovely kids, can we say that we are 融入主流社会?  Or does anyone in America prohibit Chinese Americans from getting into the so-called 主流社会?  For example, does any American like whites or blacks stop our Chinese Americans running for American president, governor or mayor, voting, going to a club or a bar, going to school, going to work or sitting in certain place in a bus or a train, plane or whatever we think that the 主流社会 should be?  I guess not, at least not that much as we think of.
To what degree, and then we can say that we are in the主流社会?  American President must be Chinese American or Canadian primer minister must be Chinese Canadian?  Do we think it is not fair to majority of whites or other nationalities in America or Canada if more than 10 percent of Congressmen and White House cabinets or enterprisers, university presidents, deans, and company executives, directors and managers are Chinese Americans?  Take America as a pie, how much percentage of this pie should belong to Chinese Americans fairly?  I don’t think that our Chinese Americans should take the entire pie or most part of this pie because our population is not that large.
If we cannot be in the so-called 主流社会 in America, Canada, British, Australia, Japan, can we be in the 融入主流社会 in China, which is our native born country?  To be frank, I doubt about it.  I can say that most of our Chinese American fellows cannot be 主流社会 either, but few like No Worry.
Does all other Americans or most of Americans discriminated Chinese Americans, but few Americans discriminate Chinese Americans?  I heard about Kuan’s case.  Is it popular in America or few extremely cases or an incident of mistakes?  Just be fair enough.  Do we think that discrimination or stereotype is much less in America, Canada, and other advanced and legalized countries than in our motherland?  I am kind of wondering why we always use Kuan’s case, not the case of Shaque to Yao Ming?  What’s the good of it?  Nothing.
If we cannot be in 主流社会 and we are discriminated abroad, what we are going to do?  Go back to our motherland of China, or stay abroad and complain or stay abroad and fight for our rights and interests?  I guess that it is most practical to stay and fight for our rights and interests.  My dear intelligent and smart Chinese American fellows, don’t we think that blacks set a great example to us?   Or can we go back to China, or can our kids go back to China if we can?  I guess not.  What are we going to do if our kids or we cannot be back to China?
Dear fellows, it is useless if not harmful just complaining, but not thinking and doing proactively, positively and creatively. America is our country, Canada is our country though we are new here.  We are working hard to be here and we had scarified much to come here.    We deserve every single right, and we should fulfill every single responsibility and obligation as a new citizen of our new lovely country.  We will fight discrimination or stereotype against our Chinese abroad if there is any.  We will fight by any mean legally for our rights and interests.  I guess that ‘s the way how we should stay abroad.
