"...the idea that you should do good with somebody else's money."

It's a bit of an aside, but Milton Friedman wasn't totally against doing good with somebody else's money. A lot of people take these quotes from Friedman and leave out his ideas which contradict the seemingly absoluteness of the statements in this video. Friedman was a proponent of poverty alleviation funded via income tax. He laid it out in Capitalism & Freedom, in chapter 12 entitled The Alleviation of Poverty. Therein he advocated guaranteeing minimum income via a system of negative income tax whereby the government pays a subsidy to people below the poverty level regardless of whether they were employed.

In this video Friedman debates his negative income tax system with William F. Buckley Jr.

Sowell agreed with Friedman on this type of welfare policy.

The implication was that this was a transitional type of system that would incentivize people lifting themselves out of poverty and would eventually be unnecessary, or less necessary.
