productively

Of course the capital of a country must be productively employed.

And note that both hands are productively employed with shorter distances to travel for stock and with decreased effort.

In past times wealth was largely accumulated in the hands of the nobility, who had no thought of using it productively.

To-day they decide to ‘save’ part of the surplus value and to invest it productively instead of squandering it.

And the converse would also be possible, B might squander it, and A might employ it productively.
