As is the case with any form of social insurance, one basic question that has to be answered is why, besides the motive of wanting ones-self to be protected, people who are unlikely to need a program like Job Insurance should support the program? Beyond the moral and ideological issue that one should support measures that help people in need and that redistribution makes a society more just, there is actually a practical reason why the roughly 80% of the workforce who are employed should support Job Insurance.
And the reason is labor market power. Between 2000 and 2008, despite several years of steady growth and nominally low unemployment, the median income of wage workers shrank, with declines being most prominently felt among the working class, because even employed workers lack labor market power.
