"Can you peacefully prepare for the autumn of your lives? Can you count on your pensions to be taken care of at least to the degree of today's pensioners? Hardly."

It rarely happens that a trade union proposes something financially smart, but the ZSSS proposed to the Finance Ministry to diversify the funds the same way as the Norwegian ministry advises the country's pension fund.

Instead of investing 50% of the fund's funds into currencies and debt securities at the time of zero interest rates, the ZSSS proposes investing 60% into equities.

This has been proposed in a wish maximise the transfer of shares of the state mastodons to the fund, but let us ignore the details, the paper argues under Forget Demographic Fund and Save.

Another weakness is investing mostly in Slovenia. Regional diversification is one of the basics of personal finance.

The portfolio that is to provide financial sustainability bets too much on Slovenian stock, which has proven a pretty rotten investment when compared to global shares.

"Thus, the demographic fund is yet another in the line of harbingers of the unsustainable Slovenian pension system and a good encouragement for giving another thought to a retirement plan," the paper concludes.
