My personal comments are as follows:
I never quite understood the IWW or why they were considered such a strong threat to the owners of capital. Utah in this interview makes clear the difference between organizing of united sectors of industry, as opposed to organizing along craft lines. In the perspective that he presents it is fairly clear that organization along craft lines, where separate crafts can be boxed out and then set in competition with each other, thus can be directed to use up their energy and resources to blunt their overall effectiveness for positive change. Organizing on craft lines seems very convenient to a corporate fascist dominance, just as public and private sector unionization is currently under pressure of divide-and-conquer. Note: Utah does point out that when workers (anyone who collects wages for their labor and does not own the means of production) lose they also win.
The Preservation Trades Network, though not in any sense of the word a union, is organized as an educational non-profit along the lines to bring together a community of related but different traditional trades within a specific industrial sector. Along the lines of stone masons with timber framers with slate roofers. There is a good deal to learn from Utah Phillips of value to the community spirit of PTN.
Quite a ways into the interview Utah mentions a conversation that he had with Daniel Berrigan. For a period of time in the 1970s, when he was on-the-loose prior to his arrest and imprisonment. I knew and spent time with Daniel Berrigan. The subject of the conversation that they had, as to the pressure of industrialization of Utah's songs, reminds me that at one point in my life I got the notion that the aesthetic work of our lives, for me it is writing, is not a commodity meant for sale. If I need to be paid I would rather be paid to move stones.
