Rounding up these idiots will be easier than falling down. All you'll have to do is have signs declaring "Free Clinic" or "Free Meds" over the gates, and close them once they are safely locked away under the local Walmart store....Once there, they will have everything they had in Mom's basement, except no computer, they will ACTUALLY have to work in the store's workshops, making the merchandise for the store, and the only thing on the TV's will be NASCAR racing (no PBS).
For those that resist, toss their current prescription in first, and they will follow....
declare a draft, and they'll all flee to Canada. That way, we don't have to clothe or feed them.
