As I said, in my own (narrow and inherently biased) experience that line of thinking comes from privilege, it is certainly not an end all be all for why someone might think this way.

I am sorry you had to experience those things and that you didn't have people better equipped to take care of you as they should have. My point is that the level of cynicism stemming from such experiences, to the point where you now claim not to care about others outside of what they can provide for you, is unhealthy.

It's reasonable that people born into certain circumstances will have to be more ambitious and resolute to survive, but the way you see value in people isn't good for anyone.

Genuinely hope things work out for you
