How would go about ending welfare?
At best We the people can make recommendations. As the numbers of people holding seats in Congress that were elected through the efforts of this plan increase, the influence on the legislation coming out of Congress will begin to reflect the goals of the people who elected them.
One could argue that some type of means and income testing could be implemented in which the people with the most economic resources lose their eligibilty for welfare first. Could a reasonable case be made for a complete phase out over a five year period, with 1/60th losing their eligibility every month?
People losing their eligibility would not be without resources and assistance; it just would not be governmental assistance. Over a period of time, it would hopefully become the case that the lucky ones are the people who lose the government's welfare as organizations and individuals gain experience and create new ways to help the people losing their eligibilty for the government's welfare. The lucky ones will hopefully discover real resources that can actually help these people to learn to provide their own means of support and regain their freedom and independence.
