Sherman Kreiner writes in Making Waves in 2003. 

Scale and markets notwithstanding, Cooperative Home Care Associates (New York City) and Childspace Day Care Centers (Philadelphia) have plenty to teach Canada's co-operators and other CED activists. Kreiner challenges CED practitioners to move beyond creating business just within ‘their’ territory; they are often poor, thus possess weak markets and often have a hard time attracting entrepreneurial and professional management. He asserts one can be often more strategic and get better results through focusing on sectors where the quality of service provided is a competitive advantage. The twin benefit of better jobs (within the sectors targeted) and higher quality service (through workers also being owners) is backed up by the evidence presented in these two cases. Interestingly, the cases he presents both are both ‘human services’.
