Wealth is much more concentrated than income, and wealth might be more important. The top 1% of Americans own 43% of total wealth, and the top 0.1% own 22%.

Also, the higher your income, the larger the fraction you can comfortably donate. Something much higher than 10% of total potential donated income will be in the top 1%.
