It might even be simpler than that. Capitalism just doesn't care past the next quarter. And when ownership is disconnected from labor or even from customer, than it's just a really rudimentary collective intelligence. The shareholders just want the line to go up, and everyone in the corporate structure is accountable to the shareholders, so they all do their part, big or little, to make that happen. It completely dispenses with personal responsibility, whether for negative externalities, direct harm, or even the future as close as months from now.
