But surely she does something, right? I'd love the opportunity to no longer work & still be comfortable, but at the same time I know I'll get bored. I like working, I just hate that capitalism forces me.

I know a few stay at home partners/spouses and all act the same: highly demanding and think they're better than everyone else because their partners are high earners despite never achieving anything in life. That's why it personally gives me the ick. Kudos to anyone who is in that situation, but doesn't act entitled.
