Sociologist Gwen Sharp's Are You Better Of Buying $200 Shoes? makes a couple of really good points on the implicit class and economic assumptions of my H&M piece.

The slightly long answer is that the cultural capital embedded in the suggestion that someone invest in quality footwear does not translate neatly into a disregard for those who cannot afford to do so. The very long answer is here, in my response, from whence the slightly long answer is excerpted.
