I'm struggling to understand this. What class of human puts other people before their own income? I'm not a landlord and I'm not putting my income in jeopardy to help a hobo out.

I rent my house to a woman who worked as a server in a restaurant until Covid. When restaurants were forced to close she offered me half of the rent as that was all she had. I told her to keep it, not worry and stay safe. This was when there was still a lot of uncertainty. After 3 months she started paying me again without me asking. Do you think I'm a terrible person?

The point of individualistic free market deal making is that it forces two people to find an overlap in their interests, then hold each other to operating within that overlap.

According to the theory of class interests, deals only happen when someone is being bamboozled. According to the theory of individual interests, deals happen when two people find an overlap in their interests.
