It's not a contest though, is it? I'm sure we can all help one another in some way, and it's disheartening to see comments such as yours discrediting (passively as it may be) the help some people give, as if their help is less worthy than others.
You may argue they earned hard for that money but some people are just lucky and don't have to struggle and are so greedy they don't care about anyone else.
The OP argued, that assuming she had donated 59B out of the total of 60B, while this would (probably) be a higher percentage than the OP, it still would not be "impressive". She would retain 1B, which, I hope we can all agree, is more than enough to live a wealthy life, and certainly more than the 3k left on the account of OP.
How is stating that his sacrifice is admirable a way to discredit the help he/she is giving?
I think the fairer point is to generalise both her and OP's behaviour. If everyone at a professional salary level was giving as generously as OP we could go a lot farther than even every single multi-billionaire throwing in a few billion.
Truth is, the entire net worth of all American billionaires together pays for about one year of national healthcare give or take. We could fleece them all and it wouldn't get us that far in the long term.
While sacrificing absolutely nothing. She could give so much more and still sacrifice nothing.
While some people may give charity as an act of sacrifice, others are aimed at helping people. The two are not mutually exclusive, but the former is not a defining aspect of charity.
I implied that the limits of her giving are not informed by any kind of sacrifice.
In contrast to me, you, and 99.9% of people giving to charity and having a limit based on sacrifice.
I doubt the goal is to impress you. While your sacrifice is admirable, at the end of the day, she's helping more people than you are.
