bro, i don't want to tell you how to live your life, but if you are describing people as envious, toxic, and potentially dangerous than either these are not your friends, or you have a horribly low opinion of people.
We don't have evidence if the problem is you or them, but I would say a fundamental baseline expectation from a "friend" is that they should be HAPPY not envious of your successes.
I found this interview eye-opening of how serious (and dangerous) money can be, when the people around you don't have any: https://www.youtube.com/watch?v=cKutkXy1Eeo&t=1178s
Even when it's not a situation of danger, though, money can still drive a wedge. The friends you made growing up, you were then equals (and neither of you had anything). Your financial success can become a mirror into their financial struggles, and not everyone does ok in that situation.
To you, that might be good, positive, and normal. IMO it was toxic and fueled by envy with no actual information to support their position (and, admittedly, no information to deny it either). They only wanted my salary information to help progress their position in life, which to me is not so different from Google or Facebook wanting such private information for their own monetary gain.
Anyway, boasting of financial success is something I find sad, unnecessary and potentially dangerous.
Tomorrow some friend of a friend junkie may need money and may think I'm collecting rolexes or idk.
Better people don't know shit.
Friends talk about friends.
Guarding your family from various criminal activities may be hard.
This all may add up not in your favor eventually.
