That's a bit of a lame argument, along the same lines as the 'trickle down' effect.

It probably depends on whether your economy is limited by consumer demand or by insufficient investments. For most developed nations it is clearly limited by consumer demand. Giving rich people more money aka 'trickle down' won't get the rich people to invest, because there is no demand (normal people already spend more than 100% of their income)

In this situation giving away money helicopter style makes sense.
