The only quick thing to say is that you have to be very careful about how you structure premiums for this. It won't work as an insurance program, if you simply allow people who are self-employed to voluntarily make premium payments and to then collect benefits. What you want is everyone who is self-employed contributing the part of the premium that would cover that benefit. I know there was some discussion of this in the beginning.
There are good reasons why the self-employed initially weren't in the unemployment insurance system. Because they are in control of their own employment, there are problems of moral hazard. But in terms of maternity leave—the funny graft onto the EI program of maternity leave, which has very different goals, as has been pointed out around the table, not necessarily the ones of the regular EI system—in principle there's no reason, if the goal of this part of the program is to promote child development or these other goals, why the self-employed shouldn't share in those goals with the employed.
