In a time of serious national emergency, many of these nanny-state dependents will begin to starve.
The enemy will appeal to them directly, telling them that if they help defeat the US they’ll be taken care of later.
That will create a fifth column consisting of roughly one-third of the total population to make mayhem from the behind the lines.
That’s a terrifying possibility. Now they are largely stupid, lazy, and unhealthy which might mitigate their usefulness a bit. But still scary.
