Uh, yes?

I give a higher percentage of my income to charitable causes than any of these "philanthropists" and I manage to not waste an insane amount of money on a disgustingly wasteful life of luxury at the same time, but for some reason I don't have an army of sycophants defending my every action on the internet.

A higher percentage of your income does not magically feed more people, nor does a "flat tax" like you propose (merely substituting "donation" for the tax) scale economically for any number of reasons.
