Pastor needs to study other countries who attempted to reunite. Example, Germany. The two Germanies reunited after the fall of the Berlin Wall. East Germany had a standard of living 1/5 of West Germany, and West Germany had to go thru financial stress to do it. Atleast the West Germans knew what was involved and voted to do it. South Koreans are facing the same issue if reunification with the North is possible. Despite their nationalistic feelings, the South Korean leaders and business community will not integrate the North immediately because the North Korean standard of living is only 1/20 of the South. These two countries understood the price of integration, and one choose to do it (Germany) with popular support, and the other is assessing it. Both countries are involving their people in the decision process. The US government and business community is doing the opposite. They know that integrating a country like Mexico with the US will cause social and economic dislocation for many of the American working class and inner cities, but they don’t care because the elites will not be affected and the cost of dealing with the problems fall on the affected communities and taxpayers. (Yet we lecture other countries about democracy). If the US must form a economic block to compete against the EU, I rather we form one with Canada and the smaller poorer Latin American and Caribbean countries who will impact the US communities alot less than a flood of illegal immigrants from a large Mexico as long as all Americans get an input on the cost and price of such a union. Current plans for the NAU is insane and undemocratic. NAFTA, MFN and etc should be reviewed and if necessary renegotiated, but both parties already indicated that they support these agreements (atleast McCain is honest about it, while Obama and Clinton say one thing in public, but privately assured Canada otherwise).
Canada has said they are more than willing to renegotiate NAFTA and they have also said that your last line is not true. The Canadian official was on c-span sometime the past week. His statements can be-found on c-span web site.
