The problem is today's society is that most people live disposable lives, they buy something, use and abuse it, complaining it doesn't work, then buy a replacement and do the same, never learning the error of their ways, from a simple tin opener to a car, people are just blissfully unaware that simple maintenance is required, be it sharpening a blade, emptying a bin/bag, changing the oil, or even just plugging it in for some!!! :S
But, that's where people like us come in, we take the things in and fix them up and either keep them for ourselves to play with, or sell them on (or even back to the people who threw it out!!! 
), but that's what separates the smarter people from the, well, "less than smart" people...
I do believe that manufacturing has gotten lazy in the past couple of decades though, aswell as making things so they cannot be repaired economically, which doesn't help matters, so combine the two and it's just a nightmare!!! :S
