Requiring an equally weighted sum would just be utilitarianism, so I don’t mean that. If you value the wellbeing of others a trivially small amount then this approach concludes it’s fine for you just to spend your money on yourself. But if you value others much at all then giving someone an extra year of life for $50 (on average) is pretty hard to argue with.
And that’s an equally weighted sum?
Until you’ve specified how “well being” is weighted in the sum, you haven’t said much. I could weight it overwhelmingly on me.
