I have heard that before out in service and at the hall. Usually, it was from a JW that was barely making it but was too "spiritual" (aka stubborn) to go out and get a real job.
One brother used to give talks where he'd always put down successful "worldly" people, as in they can't be really happy and they must be working non-stop to have the nice house and car, etc. (Really???)
Meanwhile, he was frequently unemployed or working at minimum wage jobs, because he was just too hard to get along with. But, he always blamed "this system" for being against him, and he was going to have it all in the "new system" (and have his revenge). Ugh!
Overall, I think a lot of JWs said things like that and didn't even realize how wacky it sounds. Of course, this was years ago, perhaps it's not as prevalent now. But it says something about the mindset.
