I think they're more similar than you might think.

The only way you're going to make any money -- at least in real terms -- on government bonds is if interest rates go even more insanely low so you can dump them on another superoptimistic person.

Similarly, those who plan to buy the "IBO" shares are probably expecting to profit when some good news comes up and bumps up the price long enough to sell.

They're both built on the assumption of being able to dump the security on another sucker.
