Since the factories that could have been producing consumer goods were being used to make items from the military, an imbalance in the industrial sector was created. In addition, the enormous spending on the war in Vietnam provoked an increasingly unfavorable balance of trade, which added to an international monetary crisis and menace to U.S. gold reserves in 1967-68. Furthermore, military expenses, coupled with domestic social spending, generated budget deficits which fueled inflation.

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
