That's great! It really should be more as you point out, I typically give around 30% each year. But I know that is a bit higher than most. 10%'s kind of traditional "tithing" which is why I mentioned that, but that should be the lowest probably. Of course people can also choose not to give back at all. One of the great things about being in the tech field and making an enormous salary is it gives us the power to influence the direction of society through targeted donations. One charity I've supported for years keeps trying to have a "gala" in my honor. I tell them forget it, and for goodness sake keep me anonymous. Sheesh. Trouble like a gala I don't need.

10% is what many call a 'tithe'. It's considered 'normal' for them.

(Many of the same also manage to retire quite handsomely. It's all about living within means.)

10% is totally realistic. The spread of salaries in the world spans a much greater range than 10%. I have given 10%+ of my salary to anti-malaria charities for years.
