The openingWhy this idea is overlooked

Wire harness assembly is labor-intensive B2B manufacturing that international automakers place in lower-cost economies with concessional market access, and Samoa hosted exactly this: Yazaki Samoa employed over 2,000 workers and more than 20 percent of manufacturing output before its 2017 closure (the operation was later succeeded by New Zealand-based Fero). It is overlooked as a startable venture because it needs an anchor automotive customer, factory-scale capital, and trade access, none of which an ordinary founder assembles alone. The defining honest lesson is concentration risk: the Yazaki closure showed how a single large employer's exit can gut a thin industrial base, so any entrant must reckon with dependence on one customer and one trade arrangement.
