Definition of "well off"

Of all the queer collections of humans outside of a crazy asylum, it seemed to me this sanitarium was the cup winner. […] When you're well enough off so's you don't have to fret about anything but your heft or your diseases you begin to get queer, I suppose.

1913, Joseph C. Lincoln, chapter 5, in Mr. Pratt's Patients
