Straight from the youtube explanation of Jason Riley's speech to The Heritage Foundation:
In Please Stop Helping Us, Jason Riley examines how well-intentioned welfare programs are in fact holding black Americans back. Minimum-wage laws may lift earnings for people who are already employed, but they price a disproportionate number of blacks out of the labor force. Affirmative action in higher education is intended to address past discrimination, but the result is fewer black college graduates than would otherwise exist. And so it goes with everything from soft-on-crime laws, which make black neighborhoods more dangerous, to policies that limit school choice out of a mistaken belief that charter schools and voucher programs harm the traditional public schools that most low-income students attend.
Gary Becker won the Nobel Memorial Prize for Economics in 1992 for putting much of what was said here into a quantifiable economic theory.
