The Republicans have been trying to eliminate what they view as Roosevelt's socialist program since its inception in 1935. The current plan involves tax cuts and spending on homeland security and the military. They intend to run the budget deficit up so high that curtailing social security benefits will be the only option left to save the American economy. Partial privatization will further reduce the level of benefits that the government will be responsible for.
Once benefits are reduced, public support for the program as a whole will diminish. They hope to finish off Medicare the same way.
At the same time, they are pushing good paying jobs out of the US. They want to return the country, not to the 1950s, but to the 1920s. Because wages paid to American workers will fall, the well-to-do will be able to afford servants again. If you are looking forward to having a job as a maid or a butler, this is a good plan for you. http://www.sptimes.com/2004/03/07/Columns/Dig_deep_to_fix_gaps_.shtml
