C thought that since there is only one piece of land in the country and land is non productive asset, its value must definitely go up.

Of one correspondent, non-productive though enjoying a lavish retainer, he once remarked: "I think perhaps if we do not hear from him next year, we should send him a note."

This is often a good place to start, but at some point it becomes non-productive -- or just not possible, if you max out the JVM.
