I don't think I understand your comment. There are people we don't know how to save, but there are also people we do know how to save. The Against Malaria Foundation, for instance, claims that every ~$3k donated results in the prevention of the death of a child under the age of 5 (https://www.givewell.org/charities/amf#Cost_per_death_averte...).
I'm arguing against the idea that people truly believe "every life is worth saving" even by effective altruism advocates. Effective altruism is only arguing how we should ration the resources we've already allocated to helping people. It doesn't address the fact there is a quota at all.
For people who deal with this professionally the quota is defined monetarily. For the average person its an unconscious decision. But in all cases the amount of resources allocated to helping is not defined directly by the demand.

I'm not sure how to determine what "effective altruism" is arguing, but prominent EA advocates like Will MacAskill and Peter Singer are absolutely concerned with increasing the amount of money allocated to helping people. The conclusion of Singer's most famous argument is that we have a moral imperative to donate most of our money to saving the most lives. Even personally, both live modestly and donate most of their income.
