Off the top of my head, I think people that work sales and earn commissions and any tip-based work might be the ones to look into. I imagine there's studies around those types of jobs.
Don, I just wanted to say it's unfortunate your comments about Gamergate were flagged and then unflagged. That shouldn't have happened. I appreciate you for shedding light on the whole Gamergate scandal and making sure the truth is heard. It's so sad to see people continue to outright lie about what happened.
As for your other comments on this post, it's a real treat getting to read some inside baseball about The Sims! Much love!
