I don't doubt that metal is more durable than plastic, but there's some survivor's bias in that statement. We usually think of 70s and 80s appliances being more durable because we see people still using them. The truth is that we've always had a mix of cheaply made vs durable products, and the cheaply made stuff broke years ago and was replaced. We're comparing our cheapest made products of now to the most durably made products of decades ago.
