Joint Superannuation Accounts

Australian families usually pool their finances and have joint bank accounts for running the household. When we retire, most of us will receive a full or part Age Pension and the benefit will be based on our marital status. Yet, when Australian families save for their retirement, they are required to have separate superannuation accounts. Why can’t the seven million families of working age pool their superannuation into a join account? There would be benefits for families, funds and government revenue alike.
