Doesn’t it? In very basic level price=cost of input materials+workforce+profit. Amount of needed work is directly correlated to complexity. Therefore with other variables same simpler should mean cheaper. Here some other variables may be not same. Either economy of scale is not in favor yet, standardization and production levels are still low. Or higher profits are taken.
Price is determined by what people will pay, not by the cost to produce something. This is driven by supply and demand, while complexity can reduce the available supply it is not the only factor and for many products it’s not even close to the dominant one.
As well complexity in design doesn’t absolutely correlate to manufacturing costs. Usually that’s dominated by labor, and extremely complex systems are designed to be made with less labor.
