"It’s a false dichotomy to say that you either save a life by helping a child in a poor country OR give to a water bill in the United States. You can do both in proportion to your ability."
For whatever proportion of someone's resources they are willing to give, they can choose to save lives for US$1-5k each.
Instead of providing one $1k life saving surgery and $1k water bill, two $1k surgeries could save two lives.
Sadly there is not a shortage of dying men, women and children who can be saved cheaply.
Perhaps one day there will be... if we stop goofing around.
