Class is relatively subjective and contextual. If you make 32k, you’re top 1% of the world. If you rank class by objective (especially out of context) percentage, you’d be rich at 32k. But 32k in Silicon Valley would barely feed and clothe you. Symptomatically, you’re poor. 

If you make 500k salary in nyc or Silicon Valley, you would probably be doing fairly well, with vacations here and there and being able to afford most luxuries. But if they quit/lose their jobs, they would quickly run out of finances. That sounds, symptomatically, middle class, because you rely on a stable income. “Rich” as subjectively viewed by many and clearly Ieatpickles, is when your job isn’t making your money, money is making your money.
