Final answer:
Sandel uses the story about Sam's Mobile Auto Repair to illustrate distinction between capitalism and socialism.
Step-by-step explanation:
The story about Sam's Mobile Auto Repair is used by Sandel to illustrate the distinction between capitalism and socialism, specifically one of the points of divergence between the two systems.
In a capitalist system, Sam's Mobile Auto Repair would operate as a privately owned business, driven by profit and competition. On the other hand, in a socialist system, the auto repair shop would likely be owned and operated by the government or a collective group, with the aim of providing services to the community without the profit motive.
This distinction is highlighted through the analogy of the lemonade stand, wherein a capitalist system would allow for individual ownership and profit generation, while a socialist system would prioritize collective ownership and the distribution of resources.
