Sure you can. The only reason nations avoid allowing people to become stateless is an appreciation of the burden that places on those people. But if we're pursuing a modest proposal where the government shifts its perspective to focus on "realize[ing] higher economic utility for" itself, that becomes less a concern.
At the very minimum you can "export" those low-economic-utility people by sticking them them on a barge and towing it to well into international waters where the currents will take it away (and if you're a nice government, just outside the territorial waters of some other country).
"A young healthy child well nursed, is, at a year old, a most delicious nourishing and wholesome food, whether stewed, roasted, baked, or boiled; and I make no doubt that it will equally serve in a fricassee, or a ragout."

If you kick out people you don't like and expect them to go to different countries it will end similar to those migrant boats in the Mediterranean.
