I call people “mean” and “Cheap” that give less than 1 percent of their copious income to charity (the Obamas and in Biden’s case, 0.1 percent).
Hypocrisy is a mean bitch.
Seriously, leftists see advocacy of socialism to be morally superior to voluntary individual charity.
They like to work for “non-profits” that “raise awareness” about problems so that people will lobby the government to solve the problems.
