Yeah they are... They give away much more money through taxation (which the article/study doesn't seem to consider. For instance, asking 'If you earned $500 000 a year and lost 40% of it through tax, how much additional wealth should you give away voluntarily,' is different from asking 'what percentage of your income should you keep/lose?' Perhaps one believes all people should keep the same portion of their income, and answered that lower income people should give more to charity in order to compensate for their lower taxation. The study misses this and the article concludes 'rich people think poor people should give more.' It's also an easy explanation for why even when hypothetically adopting a different income bracket, their attitudes 'changed').
