The computer industry is a prime example of an entire sector that would not even exist if it were not for decades of publicly-funded state-directed research and development. South Korea practices a form of state capitalism (common in East Asia) - national champions like Samsung are in no way independent of or opposed to the State. The work hand-in-glove with one another. Samsung would not exist without decades of special favors and protections given to them by the state, for the purpose of promoting industiralization and growth to improve South Korean society. They are not a valid example of some "free market" entity that outperforms the state, or otherwise exists in tension with it. The point is not that corporations are "in it for the good of society," but that society has no reason to allow corporations which do not contribute to such to exist in the first place - and that no corporation can meaningfully exist without the acquiescence, if not outright participation, of the broader society and state.
