It is possible that this is not the case right now. Banks are still starved of cash, if you can believe it, to beef up their "core capital". So it is possible that certain deposit or money market accounts (even some checking accounts) pay high interest rates. In addition, right now we're experiencing deflation.

I am like a child, I am like a pensioner with money to take

Widows and orphans have no place in the financial casino. So we regulate mutual funds in order to make them "safe" for widows and orphans. But in making them "safe" we make them slow and vulnerable to nimbler market players so they are just like the proverbial widows and orphans. So the widows and orphans lose their money in the casino anyway. So, the moral of the story is: if you're not safe by yourself in the casino, don't give your money to someone else to play in the casino for you.
