What you describe would never happen - don't know how anyone could possibly want it to. The horrors of revolution can exceed the horrors of any tyranny.
As man moves further from free human to being, effectively, livestock, he does so with no principled opposition to that which is going on - he can't oppose any given incremental step on its own, and probably clamored for it. He will not notice tyranny, because it won't be too different than anything he remembers.
The capacity of man without principle, for oppression, seem to not have a limit, up to, and including, his own death.
Look at Cuba. People living there have never known anything different - the only reason they possibly COULD know anything different is due to the existence of places like the US.
What if every nation was like Cuba? If a sole person spoke of freedom, he would be denounced by all as a radical who threatened the fragile fabric of civilization - and be blamed for any given famine.
Looking again at cuba, however, I fear for OUR future for other reasons.
First off, Cuba and the Soviet union suffered under marxism; but had not denounced modern technology. They did not have "environmentalists" trying to deprive humans deprived of liberty and a decent economy of the internal combustion engine as well. The marxists really DID intend for people to live better, and their vision happened to include machines taking the burden off of men.
While environmentalism for us really only serves the purpose of presenting a catachlysmic consequence to individual liberty (the lie "if you were free, you'd destroy the world with carbon dioxide", for example). I sincerely hope it does not last beyond serving its purpose - the though of a Soviet/Cuban life minus the internal combustion engine is quite horriffic.
My second concern is the capabilities of law enforcement. When the laws are not compatible with your very survival, they have to be broken. Cubans subsist through being able to trade food on the black market - the "law abiding" would starve. But they get away from it, and humans survive biologically as animals, if not being able to live as humans.
I like police to have the capability to capture murderers and thieves. But in a place like Cuba, where the government's job IS murder and theft, if the police were as competent as in the west, folk would have to become law-abiding and they would starve under unlivable laws.
But again, if you consider some sort of revolt in western nations - consider those who protest now. Those who are the loudest and most pi**ed are those who mislabel the way we live now "capitalism", and blame whatever liberty remains for all ills. Any economic problem caused by socialism raises more voices in support of socialism - win-win for them. If there were a revolution, it would be a communist revolution, not one that is pro-liberty. And any revolution such would turn the world into Mogadishu - a hell from which the chains of a Stalinist state would be a pleasurable release.
Want some hope? If there is any at all, it is in the US. In the US, there is little; but it lies in those who defend liberty not just in areas where it affects them; but as a principle on which there should be no compromise.
The best weapons are not the feeble restricted crippled guns you have; but in educating others. Another is the US constitution. It may or may not have been flawed at the onset, it is certainly defiled now regardless - but government procedures and the constitution present opportunities to stall future losses of liberty. Filibusters, getting laws thrown out as unconstitutional, electoral colleges and representative boundaries, etc.
I am not certain that the optimistic scenario is possible; but if it is, it involves:
Working within and fixing the Republican party, both bringing it to victory and leveraging the pro-liberty minority of the party to control the strength of the votes of the majority of the Republican party.
Working within and fixing the USA. Any destabilization occurs in the US (however unlikely) and we lose - socialist countries will be stronger, game over. As I said above that a revolution would likely be socialist anyway, this would be a win-win for those people.
Along the way, delete Osama Bin Laden and every other terrorist who's still wasting oxygen. Sharing the earth with them and their activities just ain't gonna work.
There are sufficient institutions at many levels in the US - with the smallest being the liberty-loving individual, the larger being America's good name, military and economic strength, etc.
Anyway, that's MY late night rant.
