Jobs ... and Jobs!

Concerning the "jobs" temporarily furloughed by the government "shutdown" --

All jobs, everywhwere in the world, either generate wealth or consume wealth. Some jobs directly generate wealth. Some jobs merely consume -- destroy -- wealth created elsewhere. And some jobs (such as the ones I have often had) themselves directly consume wealth, but yet are still net wealth *preservers* because they make wealth-generating jobs more efficient or prevent loss (wealth-destruction) elsewhere.

Some jobs which merely consume wealth are nonetheless necessary.

There is no government job, anywhere in the world, which directly generates wealth. So, the two-fold question about any government jobs is:
1) "Does it preserve more wealth than it consumes?"
2) "If it merely consumes wealth, is it nonetheless necessary?"
