ran low, intermittent periods of production were explicitly aimed at continuing travel, with the will to work almost entirely driven by their backpacking consumption needs: I see working as more just supporting my lifestyle. If I didn’t have to work, I would be travelling all the time. I’ve only once worked for more than a year in one job for the last sixteen odd years (Max, English, 40). Rather than work being a central activity of social identification, it is reconfigured here to an instrumental level that enables an identity expressed through lifestyle consumption. The decision to work casually to finance lifestyle travel was justified by Thomas (English, 29) as a generational shift away from an industrial logic of production: ‘In our parents’ day a career was something to treasure, you wouldn’t throw it all away. It’s not like that anymore. We can afford to be more frivolous with things like that now.’
