Food Co-Op is Scientology. The CEO of Whole Foods Market says socialism is a fundamentally flawed economic theory that never has worked and never will. John Mackey, who debated Marxist economist John Roemer at FreedomFest in Las Vegas last week, said state-controlled economies simply don’t comport with human nature. The co-op in my area is crazy expensive. I’ll stick to the farmer’s market and the many fruit and vegetable stands along the roadside.“I want to make the world a better place. But you have to do that in a sort of pragmatic fashion, not a utopian transformation,” Mr. Mackeytold Opportunity Lives after the debate. “There’s not going to be a new human being that’s going to pop up [so] that human nature ceases to exist, and that’s been the myth of the socialistic man, that they can change human nature.”During the debate, he pointed to data showing economically free nations enjoy greater prosperity than less free ones.And although Census data indicate the American middle class has shrunk since the late 1960s, Mr. Mackey said that’s because more Americans are earning higher incomes than previously. While just 8.1 percent of Americans earned more than $100,000 in 1967, that number ballooned to 24.7 percent in 2014.The grocery executive also disagreed with Mr. Roemer’s notion that socialism “just hasn’t been done right.”Adopting some socialist strategies such as single-payer universal health care as part of a democratic system of government? Let’s ask Norway, Japan, the UK, Kuwait, Sweden, Bahrain, Brunei, Canada, the UAE, Finland, Slovenia, Italy, Portugal, Cyprus, Spain, and Iceland.
