I'm all over the map on this issue. I have both vintage and modern machines. Back when machines were made to last 100 years, most households had to buy them on time, and had one per household. Now with plastics and foreign labor, machines aren't made as well, but we can afford to have many of them. I have a longarm, a sitdown, embroidery machines, piecing machines, class machine......so do most of us...so is tossing them every 20 years worth it or not? For me it is.
