Just found this sorry it took so long. and welcome to the site.
If the cracks are new in an older house, yes you get excited.
Usually these cracks occur in the first year or two becuse the dirt below was not good enough to carry the weight of the building. Then it is a waterproof and level problem.
Unless there is a real problem that needs to be fixed, usually all that is done is fill the crack to make it look good and waterproof and re-level the house without really fixing the foundation.
The nature of the stemwall crack, being much wider at the top than the bottom, would indicate that the wall to the left of the crack is rotating downward. Further investigation should be done to determine why it's happening, and then proceed with a structural repair if warranted.
While cosmetic repairs may make the owner feel good, they usually do little to enhance the integrity of the structure.
