Maybe I am amoral, but I don't value myself the same as a random person even in a theoretical sense. What I do is I recognize that in some sense I am no more valuable to humanity than any other person. But I am way more valuable to me - if I die, that brings utility to 0, and while it can be negative in some circumstances (aka Life is not worth living), some random person's death clearly cannot do so, people are constantly dying in huge numbers all the time, and the cost of each death is non-zero to me, but must be relatively small, else I would easily be in the negative territory, and I am not.
I'd like to hear from people about a process they use to decide how much to give to charity. Personally, I have very high income, and while we donate significant money in absolute terms, in relative terms the amount is <1% of our post-tax income. It seems to me that it's too little, but I have no moral intuition as to what the right amount is.
I have a good intuition on how to allocate the money, so that's not a problem.
Background: I have a wife and two kids, one with significant health issues (i.e. medical bills - possibly for life), most money we spend goes to private school tuition x 2, the above mentioned medical bills, mortgage, and miscellaneous life expenses. And we max out retirement savings.
If you have some sort of quantitative system where you figure out how much to spend on charity, please share. If you just use vague feelings, and you think there can be no reasonable quantitative system, please tell me that as well.
Update: as suggested in the comments, I'll make it more explicit: please also share how you determine how much to give.
