There is so, so much work needing to be done, so many millions and millions of jobs needing to be done... but in our current economic-political system, what makes a job is not that it needs to be done, but that it is needed to keep the current capitalist economy going.
I work in a hospital where there are critical, dire shortages of nursing staff, teaching staff, doctors... everyone. Go to a public child care center: do you think they could use several more great (and well-trained, through enlightened and free education) staff? Class sizes in high schools and community colleges: do you think really it would be good if we hired more teachers? How about cleaning and beautifying and greening (radically greening, actually) our cities (which lifts everyone's spirits, potentially unleashing more positive and creative works)? Any jobs needing to be done there? Or how about radically greening our whole civilization so that we just might avery entirely cataclysmic climate change and other environmental disasters--any work needing to be done there?
With enlightened and solidly people-powered leadership, any transformation is possible. The question is, how do we create this?
