Every family should have a gun,
a vegetable garden,
and two chickens.
Just think how much better this country would be even with THAT level of independence.
And make sure you have natural crops. Don't use GMO sterilized Monsanto "terminator" seeds or else you'll have nothing to eat the year after. And for chickens, get 3 hens - 2 for eggs and 1 for breeding, and 1 rooster.
And if you live in the city, God help you. There's a storm brewing. Better make provisions now.
