Thomas Sowell: "we need to focus on Facts about Results"

One of our favorite writers, Thomas Sowell, speaking at a conference way back in 1980, unearthed at Youtube.
It's incredible to think that this speech is being delivered over 25 years ago, from surveying the 1970s.
Here's a highlight:

"Looking ahead to the future, one of the things we need to focus on, are Facts about Results, not rhetoric about intentions. We need to look not at the noble preambles about legislation but at the incentives created in that legislation.
Very often legislation intended to help the disadvantaged, in fact pay people to stay disadvantaged."
