STEM THE FLOW, PLEASE.
We are all immigrants.
I, myself, am an immigrant, and it would be hypocritical on my part to say that immigration reform should be formulated with the future of the United States in mind, more than having the political landscape changing for the sake of votes.
America is, and will continue to be, a melting pot, a "mixed bag", a conglomerate of cultures, a nation of immigrants; and so on, and so forth.
However, the underlying factor that has sustained its mantle to be a principal and influential entity or player in world affairs is its background of the western way of life, whose expression in all kinds of innate documentations to establish it as one nation, has been captured in the English language.
Its constitution and the bill of rights, which are the "bloodline" of its political, social and economic life, have come from the English language; and as such, its form of government has been deeply rooted in the parliamentarian system, without monarchical attachment of any kind, of course.
What will therefore be very disturbing will be the overflow of people, who are bound to introduce a new fangled culture and language to totally upset its (America's) status quo.
Ideologically, no one will be able to pinpoint what the U.S. will be, or how its geo-economic structure will look like in twenty to fifty years from now. Yet, not many people will want much to change for future citizens, as they find life in America today; unless its borders are not securely protected, and "immigrants" are allowed to enter the country illegally.
That is what a great majority of Americans are afraid of; and therefore, political objectives are important, to have the presence of other people translate into votes, it is also necessary to consider the outcome, when the present day basic culture is completely displaced to make America become transformed into an entirely different place, looking thirty or so years ahead.
Reform? Yes; but stem the flow over America's borders.
