Most people have hardware that is capable enough to create much better, more compelling images than what they are used on now. So, the wife really does understand, which she can because she is not a gear geek. I spend a lot of time in world class museums and I have yet to hear a viewer of a great piece of art "wow, look at that sharpness, must have used great brushes". Good photos are rare, but decent gear is very common. Just face it, most of hobbyists are gear geeks who like to play with and talk about gear, but very few have a true talent in creating art with photography. A lot of the pros are just technicians, journeymen, not creative, doing the same routine poses and lighting set ups year after year for weddings and portraits, and make their money by being cameras operators.
