If I understand your argument, you're saying that I'm a 'creditor' to my bank when I deposit money there that they are obliged to return on demand.

So if I find a dollar on the beach and pick it up, what liability has been created by my having a new asset? Are you saying that the potential to find the dollar was some sort of collective asset that I've turned into a liability? That seems like an unnecessarily complicated way of looking at things.

The only thing that can keep the pension system going is a growing population paying into it. Pensions are the ultimate pyramid scheme, the idea that bonds are a safe private asset... safe compared to what, and how safe on an absolute basis?
