These both seem like kind of naive programs, but the latter has the convenient feature that it requires no challenges to existing power structures, nor dropping out and living according to newfound values. All it requires is making a lot of money in some professional role and giving a chunk of it to the effective altruism people who will make sure it gets used according to best utilitarian principles.
So the SSC scenario doesn't have much to do with Rawls actual Theory of Justice. This is not surprising. The politics of SSC and of "Rationalism" more generally do not have a lot of time for justice – they may not be right-wing, but they are definitely against "social justice" in all its forms. Their preferred method of helping the unfortunate is mechanized and rationalized charity (effective altruism), not the universal rights of a liberal order. They are broadly libertarian, and a Rawlsian society relies on a coercive and redistributive state to ensure justice and fairness.
