... for employer of last resort programs, the cost of the wage is not charged to the activity, its charged to the general fund, so the question is, what activities are worth their on-costs?

Between environmental remediation, sustainable infrastructure provision and direct provision of increased social services, all budgeted on the basis of on-costs after labor cost and so strongly biased to be done in as labor intensive a way as practicable, employing 10% to 15% of the workforce with Job Guarantee jobs is do-able.

Of course, once a substantial fraction of the unemployed are provided with Job Guarantee jobs, there will be an increase in private employment as well, so its not as if the Job Guarantee has to employ the entire 20%.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
