Triggering the fail safe caused a brief "rip" in time when the sky turned purple. This rip carried the Island, it's contents & nearby islands back 50 years in time. Their communications are down as the Others most likely rely on satellite or long range radio which didn't exist in 1954 and why rescue is now even less likely.
The Other's very quickly realise they are back in 1954 (as they had been expecting it) and that it won't be until Hanso comes along in the late 60's and finds them and the Island until they have contact with the outside world again. Until then, the make a truce with the LOSTies and the live together on the Island. Supplies soon run out (no more food drops) so they learn to farm and live off the land. Due to lack of decent medicines etc, people are dying all the time and the numbers soon thin out.
Hanso comes along in the 60's, finds them and hears their story. Hanso realises the Island is special (moving in time) and notices the electromagnetic anomalies. He leaves the remaining Others/LOSTies on the Island so the world doesn't learn the truth and he sets them up in Otherville.
Hanso then sets up the hatches and infrastructure using the De Groots, Dharma and the Valenzetti equation as his cover so he can secretly unlock the secrets of time travel for his own purposes. The Swan and the button were set up in order to keep the electromagnetic build ups at an almost unstable level that was still containable. Hanso knew that it was due to the failsafe trigger in 2004 that the Island travelled in time so he needs to keep the electromagnetic anomaly "bubbling" away until then at which time he'll witness the time travel first hand and unlock it's secret.
The incident in the 80's may well have been a revolt by the trapped Others/LOSTies against the Hanso/Dharma people and ran them off the Island. Hanso needs the Others to be alive still in 2004 so allows them "supervised" contact with the outside world and continues their food drops because for the events to play out the same way again.
By the 90's the Others are all growing old so Hanso starts "recruiting" new people to the Island. Little did the recruitees know but it's a one way ticket as Hanso blocks any attempts for people to leave the Island and have the world find out. May explain why Ben let Michael & Walt go so they could alert the outside world to their existence and thwart Hanso's master plan.
2004 comes, the plane crashes etc. The Other's know they need to stop the LOSTies triggering the failsafe to stop Hanso which is why they spy on them first and don't make themselves known or offer help. They also know it is Desmond who has the key and is the one to turn it. Ben allows himself to be captured to get into the Swan to find out if Des is there or not. In "Lockdown" when Ben tells Locke he didn't put in the numbers and press the button and nothing happened (even though he did enter them) was so that Locke would also not enter them next time leading to an electromagnetic overload/meltdown and without Des around know one could use the failsafe key and cause the time slip. Ben probably didn't care what the overload would do as even death for the Others would bring an end to their imprisonment on the Island.
Problem is Des turned up just in time and uses the key. The Island slips back 50 years again. However, as Des was at the centre of the time flux in both time-lines when he uses the key, this time it blends the 2 Des's from different times so he has both memories and therefore remembers what is going to happen on the Island for the next 50 years making him seem prophetic.
What this means is that the LOSTies became the Others.
The youngest of the 2004 LOSTies would still be alive 50 years later while the older 2004 LOSTies (say over 25) would have all already died on the Island after being there since 1954. Adam & Eve = Kate & Sawyer or Juliet & Jack, Ben = Aaron, Claire or Cindy = Amelia, skeleton in bear cave = Locke (in his favourite Pearl t-shirt).
The older 2004 Others (over 50) knew when the plane crashed that it was their younger selves arriving which is why they were so hellbent on getting the children so they could keep them safe and healthy to grow up into them (after the time slip). The LOSTies referred to as good ones are the people who become the future Others, those not on the list die early on or don't contribute to the future of the Others.
Congrats if you made it this far. Sorry if this has done your head in a bit but I even gave myself a headache thinking this through. I think a lot of LOST can be worked into this theory but I'm sure someone can point out it's glaringly blatant faults for me.
