Hate/disrepect towards people for reasons that they cannot easily change about themselves (especially ethnicity, gender, and sexuality). And also violence in general (I'm OK with fictional violence, though).
If you don't have to worry about money (or bills, or debt), you only need to worry about feeding yourself every day (food and water). So it might replace one set of worries with a different set...... which is probably fine for some people.
I don't know, some low-level office job in the government? I actually think most jobs have some element of stress in them, although not necessarily on a regular basis. I don't think any job is 100% stress-free.
What single piece of technology makes your life easier?
iPad (if I didn't get an iPad as a gift a few years ago, I would've gotten myself some other brand of tablet). It has replaced my laptop in many cases, but it also complements my home and work computers through remote control apps.
