Chances are your retirement funds are stuffed together with investments in tobacco companies, pornography, gambling casinos, weapons makers who support oppressive regimes, assorted major polluters and biotech giants like Monsanto who genetically engineer your food.
Your pension plan is designed to pay you a specific amount of money at your retirement. To make your retirement money grow, the company you work for invests it not on your behalf but on their behalf. Instead of investing it in something safe like bonds, some companies and governments invest your retirement money in the stock market. They gamble your money and collect the profits for themselves.
