The democratising potential of workers’ capital has sometimes been used as a justification for privatising retirement security and the integration of workers’ interests into financial markets. This potential has been somewhat over-stated. It is true that institutional investors, especially pension funds, have rapidly increased in size and market share over recent decades. But this shift in the ownership of capital has not resulted in a shift of control. In Australia, some superannuation funds provide scope for workers, through their unions, to have an influence on investment strategy. In practice, this influence is very limited.
