though "what you actually get" in the long run includes superannuation in Australia, but people do not count it as a component of their gross income.
( It was a clever mind hack by the Keating Labor government to have super not be a subset of your base salary, but rather as an on-top-of entitlement for employees—or from the employer's perspective, an additional wages cost just like payroll tax. Had it gone the other way, people would be more sensitive to their earned money being locked away. )
Even though that doesn't financially penalise me, it still feels a bit mean. From the company's point of view though, I'm sure they'd view it as far more mean if the government suddenly told them they're obliged to pay everyone more.
