RE: I’m really not stoked on “clients” who take a bunch of my precious time and then refuse to pay me for my work.

This sucks :( But yeah, as you say; Karma is balancing things out. If they can't afford to pay you for your marvelous art, they are probably struggling financially. And they are probably struggling financially because they lack integrity. Keep up the fantastic job you're doing, and Karma will reward you plenty! :-)
