I've posted this before, I'll post it again.
1) The released workers means that the government no longer needs to pay their salaries.
2) The money saved from what would have been spent on the salaries stays in general revenue.
3) More funds in general revenue, if we hodl our government accountable, means that gov't debt can be paid off or taxes can be cut.
4a) Assuming taxes are cut, the money stays in the economy.
4b) Assuming debt is paid off, that means the government saves more money by not having to pay the interest on that debt, which means they need less revenue the next year so that taxes can be cut; the money goes back into the economy, and the tax cuts on top of that leave more money in the economy.
5) That additional money in the economy creates jobs.
6) Guess who is sitting on their couch ready to fill those new jobs: the old IRS employees!
Simply point to WWII G.I.s as an example of how readily the economy reabsorbs government workers.
