What is wrong with people who do everything at expense of others if it benefits them.

People who consistently prioritize their own interests at the expense of others often exhibit a lack of empathy and a tendency towards narcissism. This behavior can be attributed to various factors, including upbringing, environment, and personal values.
I generally stay away from those types of people unless it’s absolutely necessary like family . Then it’s very limited contact only .

I think this is the world we live in, unfortunately. I call it the “what’s in it for me?” mentality

Stop talking about me

Don’t you tell me

Sounds like Donald Trump to me!!!
