It can be tougher!
If you ever go to an automobile wrecking yard, take apart something
electronic on a vehicle which has to do with safety. Like an anti-lock brake
electronic control module or an airbag monitoring module or the airbag crash
sensors. These things are built like a tank!
Then take apart something which does not have anything to do with safe
driving, and if it breaks, will not cause any safety issues. Like electric
door locks, power windows, power trunk release, etc. These are all a piece
of junk! And the switches which control these things many times will not be
sealed. This allows dust to get in and the switches stop working after a
period of time.
They want things to break, When things break, they get added revenue from
repairs. Some people will purchase a new vehicle instead of having these
things fixed. It means money for the dealers and manufacturer!
Actually I have seen many lower end products be better quality and the
higher end products have all sorts of things which are designed to break and
need service. I think they do this thinking lower cost product buyers don't
have the money for repairs, but higher end product purchasers do.
