Making "friends" or being treated good when you have some sort of status; be it money, job, skills, fame, or otherwise things that show those things to others, is ez mode. Everyone will treat you good and everyone will try to be your friend whether you like it or not, but that doesn't mean those "friends" have your best interest in mind.
I always tell people i have no job and no money.
What people earn or the amount of money anyone has is no one's business, and you should never ask that to anyone.
Normies usually go full mask off and you can filter them easily because you just destroyed the only two things they can talk about.
Also people who ask those questions mostly seek status or opportunity themselves, you don't want to surround yourself with people like that that will betray you for a handful of pennies.
