IMO high tech cost optimization is like the opposite of chabuduo - it's not half-assing, but over value engineer under pressure. The PRC's "amazing" manufacturing system fosters adversarial competition down the supply chain because there are so many competitors, packed with technical talent incentivized to value-engineer the shit out of everything to squeeze out fractions of a RMB more per unit. Some engineering team probably poured thousands of man-hours and retooled $$$ manufacturing lines just to gain a tiny margin edge. Sometimes that backfires. But the pressure isn't about laziness - it's involutionary effort. The result is still a zero-trust environment, since when manufacturing base is so dense, everyone incentivized to cut corners or optimize/tweak silently, they usually do, forcing everyone upstream to stay hyper vigilant. So we end up in default equilibrium where it's cheaper/more optimal to squeeze downstream and inspect.
