I take it you don't have kids. It doesn't matter how long the toy could last, they'll still only play with it until they get bored then it gets lost or ignored.
It's the same with most things that are continuously being improved: another poster made the point about cars. Most people don't want a daily driver that's a 30 year-old gas guzzler even if it still runs fine. New cars are more comfortable, cheaper and have lower operating costs.
It's not going to change: people want stuff. The cheaper it is, the more stuff they can have or the less they have to pay for the same amount of stuff.
