how do you handle the salary question among friend circles/relatives/strangers?

i come from a lower middle class background, and my friend circle's family were in similar ranges(some had richer families).

my parents struggled hard to get me into tech and fortunately tech is hot right now, so currently the today's situation is that if counting the individual's income (not the family) then i maybe the highest warner among them (1 is a lawyer , another is a teacher, another is an amazon delivery manager, plus there are a few others).

my problem with this question is that its none of their business. firstly, i am all that my family has. these guys have richer brothers, fathers and sisters their total income is way more than mine. and even if i earn more, i don't earn to be the rich spender of the group. and i neither can be their sole source of hope in case anyone ever needs any money.

and more so fucked up shit is the fact that friends are ruthless and starts discussing this stuff anywhere. like we are among the strangers for fucks sake!! and knowing the state i live in , some of these guys could follow me and burst my guts in the name of money, which i fucking don't have!
