Although i understand the frustration at this I personally would prefer money in hand than salary sacrificing.
Why would i salary sacrifice if i cant touch the stuff for 35 years. Why would i salary sacrifice and leave myself open to ever changing superannuation laws? Why would i commit more to super when stocks and super schemes have gone nowehere for years (cap gains) and promise negative growth for years to come...?
Salary sacrifice isn't for everyone, obviously. But for certain people, in certain circumstances, it is a great option. As lizzie said, it is hard to beat a tax free income for life, if you don't have much else in the way of investments outside super.
