externality
Externality is the phenomenon where the effects of an economic activity latch onto bystanders, imposing unseen costs or benefits. Whether good or bad, it always sticks to someone’s neck, scattering invisible burdens or windfalls. Politicians and economists discuss it in numbers and graphs, but actual victims experience smog choking postboxes or noise pounding windows. It’s a ghost that defies the market’s omnipotence, and a mirror reflecting humanity’s ego in pursuing self-interest.
