I have a wide angle lens, and if I recall correctly, getting the background to blur is harder for the short focal length.

This one is very wide and still blurs the background.

(who knows, it might not be anything out of the ordinary)

Depth of field increases as the focal length decreases. It's exceptional enough that there are very involved manual procedures for taking 10-20-30 pictures with a telephoto lens wide open, and stitching them together to give a wider angle appearing picture.

Completely spit balling, but I suspect that front lens element is worth about as much as a house.
