Is NOBODY wrong in the post ? POST : This may not suit this sub as it hasn't happened yet sorry if so.

I will be attending my SOs workplace award night, one of the other wives is head of one of the major "fast fashion" (cheap clothing with new styles hitting the store every week) womens clothing chains in Australia. 

I guess I'll factor her personality in to this; She is absolutely dripping in money and she unashamedly brags about 6 star holidays her and her toy boy take every few months. She also brags about the $2,000 bottles of tequila she loves *"and I drink allllloottttt of that tequillllaaaaaa!"*. So she likes to brag and remind you how poor you are. Shes horrid tbh.

I have found out this company is manufactured in a province of China that uses child labour. Ive also found out they have a poor environmental record. I feel like I should say something as these are things I find abhorrent.

Should I mention this in conversation at this event? (which will be the only time I see her until the next Christmas party.)

So will I be the asshole for doing this?
Should I confront her?
