I think that is about the normal percentage of prepared to not prepared.
Even if we say only 20% are prepared that is still 1 person out of 5 who is good to go.
When I look around at different places I have to think it is actually pretty good to get 1/5 of the people prepared.
I would like to see it the other way around with only 20% unequipped for emergency, but I doubt if that will ever happen.
