I take your point about economies of scale and mass production- guess we are all familiar with the HENRY FORD model of manufacture compared to the previous hand built cars and the stark contrast in manufacturing technique dropping the purchase price. However most mass market manufacturers now fall within the same investment envelope curve Putting it in other words the relative unit costs of producing 100 shock absorbers is much higher than producing 100,000 when you take into account tooling up a production line---that said I suspect the cost curve of producing 1,000,000 doesn't change unit production cost much over 100,000. The trick is to convince people that their product is on a different part of the unit production cost curve than it actually is to justify the increased purchase price.
In a general sense you are right, the real issue boiled down is in house manufacture versus out sourced through a multi national suppliers like TRW who I cited previously.
As long as the original blacksmithing manufacturer of say valve springs can "enjoy" a fixed price over the contract period then all is well contractually on almost all fronts
.
We don't however live in a perfect world, and a fixed price for a unit run can potentially cause serious financial difficulties for the original supplier, notably the original
Rubbermaid brand and Walmart comes to mind.
But staying with "motors" for the minute a let's say TRW contracts with a popular UK fictitious car brand called
The Boccarini Super Sports Cars Company of Podunct Town UK.
The original spec is solid drawn Swedish alloy wire for valve springs.
TRW contracts with British Steel to source the raw material i.e. the
right specified wire from Sweden for a fixed price .
The price of specialty steels suddenly rises and the Swedish cannot supply for that price so they claim
Force Majeur circumstances in the contract.
TRW now looks to source elsewhere due to
their contractual obligations with Boccarini and finds a Polish company that can supply an
equivalent for a much lower price securing profit margins.
The Polish company has in fact signed a
secret deal with a Russian steel maker who actually supplies the material through the Polish company as a pass through activity..
Suffice to state the valve springe go "soft in service and engines are blowing up all over the place almost bankrupting poor old Boccarini in the process of warranty claims and lost customer confidence.
Sound familiar?
It should do, it happens every day with out sourcing.
