Household appliances have become much cheaper (inflation-adjusted and also in terms of hours worked to buy them) in the last 50 years so people are actually saving money. I don't see how you tie any Federal reserve/Central banks policy to the longevity of products.
Indeed, if products were getting cheaper in absolute terms (via deflation) not just in relative terms (inflation-adjusted, as is the situation now) this would not lead to people buying high quality products which last because the expectation would be that they would be cheaper to replace in future.
