Let's face it--if they bring armies of National Guard to go door-to-door--as they did in Katrina, getting people's guns, even those on dry land--we've had it, no matter what. What's more likely, as Alex Jones says, is that they'll set up the bread lines and we will eventually go to them. When they say, "Whenever you run out, you just come on down to the barricades, we'll register you, and we have all the soup and bread you want, clean water", etc., then we will eventually do it. It's that or suicide. You can prepare for whatever Mad Max scenario you want--but that was in Australia. You want to ride around on dune buggies with your gym partner and get a mohawk and play shoot-em-up?
Go to Australia. I don't know that you'll be any safer, but that kind of thing won't happen long here. You might get a few days of it on beaches in California, but as long as you're within range of the U.S. military, you're a bug to be squashed.
The only scenario in which we stand a chance against the NWO is one in which they have to fight as hard as we do at the same time--like, say for instance, a zombie movie. If there are massive infestations of something that keep them busy, then it takes their eye off the ball.
Unfortunately, zombies are fiction.
The usurpation of the American economy by design, by whatever group is doing it intentionally, is not. Neither is the eventual survival mode in question here. Hoarding storable food and water is good--but having the ability to take that away away from others is better. Let's be real--when somebody finds your hidey-hole, if you're not well-armed, they can either make you irrelevant or march you out to save ammo.
So, no matter what--buy guns, get guns, and whatever larger caliber weapons you can find--and know how to use them. We're talking about a real-world situation totally unlike this one--so you'll need to arm yourself not only for the fall of society, but also society's power grid. Unless you've got friends in Dr. Steven Greer's group, you're going to need power, generators, gas, etc. Whoever has the ability to wait it out the longest while using the smallest number of calories with the greatest amount of stealth is going to have the best chance to get out alive, or at least last the longest.
There is strength in numbers, so I guess my answer would be to hang out with like-minded individuals with variable and adaptive skills. Find people that know how to hunt, gather, farm, protect, salvage, find resources, and defend what they already have. And, you'll also need to find somebody that has the charisma necessary as a leader to talk to the raiders that will inevitably come around and try to dissuade them from taking, and turn them around and convince them that joining the collective (a la the Ultimate Warrior w/Yul Brenner) is a better way to go--you have to have people that are willing to bargain and wheel-and-deal. In an aftermath situation, for whatever reason, the ability to bend not break will become a survival tool discovered by any and all that decide to stay in the game.
Basically, you have to make yourself invaluable to people that have the assets and resources you're going to need, and you're going to have to have the ability to go mobile at a moment's notice. On whatever level you find yourself. Many, many writers have envisioned scenarios like this, so there's actually a pretty good amount of already-established data to draw on.
Overall, don't forget that there isn't going to be any currency worth anything except maybe for the government. The people that are still out there are going to be involved with each other on a barter system--and probably most of that will be for bulky, big, perishable food. Heads of fresh lettuce. Cartons of tomatoes, viable seeds--you may be able to get away with smaller barter units like shotgun shells, etc.--but the day-to-day needs of other collectives will need to be met, and those are going to be the market forces in play. It's going to be a seller's market, not the other way around, so you'll need to have as much variety as possible. The willingness to look to fill the needs of others (I believe the kind of character is called a "fixer" in some of the role-playing scenarios) will be most important.
And if any of these barter/survivalist communes are going to survive, wealth after the fall won't mean much. The preparedness of those that had wealth and shifted it into resources before the fall (adaptive wealth) will be paramount to their own survival. Having really nice mansions in the Hollywood Hills isn't going to be enough in situations like this.
For individuals, putting down the pipe is going to be the short-term answer. If you really feel that this NWO-Bilderberg-polce state fall is coming--and that certainly is something that many people with their ear to the ground believe--then the "continue to get stoned and play videogames" attitude will only serve you for as long as you can get whatever it is that you're smoking and electricity.
After that, the ability to do the above will be the only real keys to survival. You can bay at the moon all you like--the moon doesn't care.
