Whole different world now then back then. Do you really what to depend on FEMA to bring you food? Yeah why not they have proven to be stellar in handling emergencies.
Also depends on where you live, some places will pull together some won’t and there will be panic. Some that pull together will depending on how bad will eventually crack under the pressure if the epidemic is serve enough.
Yes, I do expect them to bring me food if they tape a quarantine sticker on my door and tell me not to leave the house for 30 days because I am infectious.
