Abstract

Equity rights are the rights required for the equitable promotion of life prospects. They include negative opportunity rights, positive opportunity rights, and social insurance rights, including disability insurance, health insurance, retirement insurance, and maintenance rights. Social insurance rights establish a social floor without holes. This explains why they are inalienable and why making them inalienable is not paternalistic. The chapter compares his account with R. Dworkin’s account in terms of social insurance markets. He also compares the social insurance rights endorsed by the main principle with the basic income rights favored by Van Parijs. He explains why Van Parijs’s proposal would have a benefit-spreading effect that would not be endorsed by the main principle.
