Here is the voluntary debt servitude scheme in capsule form:

Colonel Edward Mandell House is attributed with giving a very detailed outline of the plans to be implemented to enslave the American people. He stated, in a private meeting with Woodrow Wilson (President 1913 - 1921),

Very soon, every American will be required to register their biological property (that's your children) in a national system designed to keep track of the people and that will operate under the ancient system of pledging. By such methodology, we can compel people to submit to our agenda, which will affect our security as a charge back for our fiat paper currency.
Every American will be forced to register or suffer being able to work and earn a living. They will be our chattels (property) and we will hold the security interest over them forever, by operation of the law merchant under the scheme of secured transactions. Americans, by unknowingly or unwittingly delivering the bills of lading (Birth Certificate) to us will be rendered bankrupt and insolvent, secured by their pledges.
They will be stripped of their rights and given a commercial value designed to make us a profit and they will be none the wiser, for not one man in a million could ever figure our plans and, if by accident one or two should figure it out, we have in our arsenal plausible deniability. After all, this is the only logical way to fund government, by floating liens and debts to the registrants in the form of benefits and privileges.
This will inevitably reap us huge profits beyond our wildest expectations and leave every American a contributor to this fraud, which we will call “Social Insurance.” Without realizing it, every American will unknowingly be our servant, however begrudgingly. The people will become helpless and without any hope for their redemption and we will employ the high office (presidency) of our dummy corporation(USA) to foment this plot against America. -


The pledging thing runs afoul of the Constitution and the 13th Amendment, so they had to make it voluntary, but to make sure everyone volunteered, they plied the media with rumors and misinformation, implying that one could not work without a Social Security number. Then they constructed the agreement with implied consent, guessing correctly that few Americans would study the law enough to figure out what they were doing. Since that time they have also been working hard to eliminate the common law, as it contains those nasty unalienable rights, and the sheeple are hard to manage when they believe they have rights not given to them by government. The whole purpose of this scheme (besides banker profits) was/is to get the public to believe that the government is above the people (a benevolent parent, a God substitute), whereas the Constitution was purposely written to make it clear that the people are above the government. A switcheroo in the battle for the money power.
