Don't be so dismissive of a new paradigm.  Just think about how many Americans have been bamboozled into thinking Peak Oil is just a "conspiracy" of either oil companies or environmental extremists.  Ask yourself why something so important as Peak Oil would be virtually ignored by the mainstream media and not addressed in a meaningful way by any past or present POTUS or the U.S. Congress.

It is not only possible the power elite are trying to eliminate our borders, it is in the works right now.  The principle backers are the members of the Council on Foreign Relations, of which most high ranking politicians are members of or affiliated with.  This goal is supported by both the neoconservatives and neoliberals.  

Get informed.  Start by reading several books on the history, process, and goals of globalization.  I must have read 40 books and hundreds of analyses by political scientists and historians to understand what was happening and why.

Although not a scholarly text, I found Crossing the Rubicon very illuminating in its probing of the corruption and scheming that goes on regularly by high ranking pols and CFR members.  Rubicon's author, Michael Ruppert, may seem to jump to conclusions but his work as an investigative journalist is topnotch.  Historian Kevin Phillip's new book American Theocracy is also good primer on the hubris of our political elite and how their reckless behavior has made peak oil a much more dangerous proposition for us all.

We have a de facto open border policy now with the biggest supporters being the corporatocracy led by none other than G.W. Bush.  It is quite obvious that if you crack down on business hiring of illegal immigrants then you effectively close down the borders.  So, we don't need a conspiracy theory to see what is clearly out in the open for all to see.
