Actually, i think the problem (well with younger buyers anyway) is that people really just don't realize that there are better options than getting a department store bike. Hell, when i got my fs bike from costco when i was 13 i didn't even know here were such things as bike stores. It was either toysrus, canadian tire, walmart, or zellers. Or perhaps this is only an experience that i share as i live in a suburb with one ****ty bike/badminton store that opened last year.
However, my fs bike did last me quite a while. It put up with all the abuse i put it through until i messed around with the derailler adjustments and the hangar got sucked into the spokes....but that was my fault. Luckily, at costco, everything is refundable...haha...even after being its been destroyed.
