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.
