A single individual cannot carry the world, the people just carry themselves.
Your comment is little confusing.
The Title “Atlas Shrugged” is symbolic. Atlas carries the world on his shoulders in mythology. The book illustrates the premise that we, as individuals, are responsible for our own actions & decisions and we must remain true to ourselves and our values. We need not and should not warp ourselves because others demand it, nor should people be given things, positions, purchase orders or power from a sense of fairness. Those things must be earned by actions and achievements. In condoning parasites we enable them and damage society as a whole.
When Atlas shrugged he realized that he was not being noble carrying the world; he was betraying himself and enabling the destructive force of “social justice”. Atlas needed to let the world stand on it’s own, step away like the protagonists. Atlas,the protagonists, then were free to pursue their own goals, cooperating with like minded self sufficient individuals, unburdened by false guilt.
