Does affirmative action place minority students in colleges where they're likely to fail while depriving other applicants of the chance to attend the most challenging schools where they are capable of succeeding? Does rent control drive up the cost of housing, depriving property owners of the same opportunity to profit as any other investor while driving down the quality and quantity of the housing stock? Do minimum wage laws reduce the number of entry-level jobs, making it harder to escape from poverty? Because compassion, by its nature, subordinates doing good to feeling good, these are questions the warm-hearted rarely pursue.
