What a weird opinion to hold in a society totally dominated by incentive. Serving yourself is
the entire point since we have structured nearly
all of human existence around incentive instead of command. Discounting the argument that it would help the poor (objectively) because it helps the person making the suggestion is like being angry at the sky for being blue. The incentives produced the outcome and should in no way surprise you.
That’s why people who act selflessly are notable. You’ve got this backwards. Selflessness is notable. Selfishness is par until all of Maslow’s is handed to you free of charge. Noticing someone is advocating for an improvement to their situation, even disingenuously, is equally pointless with that in mind.
People do things in their interest because that’s how we have built human civilizations that pay any respect to the concept of freedom. If the suggestion benefits others, maybe go with it? Or build a civilization where everyone can be selfless all the time and have no self-serving motives; that sounds pretty great until you get to the “how to direct an economy” part of the equation.
