The old left had the problem that its roots were industrial, so there was a tendency to think of "jobs" and "worker participation" in centralised, large-scale, industrial terms.

That was partly the legacy of Marx, for whom the "means of production" were industrial.

There are signs it's starting to ease, and there's a hint of a tendency towards diversification and more free and organic forms of participation.

What's missing on the left at the moment - at least in the UK - is the usual need to move beyond oppositional theatre (e.g. UKUncut) towards demanding seats at the policy table for all issues, not just single-issue campaigns.

That may be starting to happen in Spain. We'll see.
