Typical moron. Always assumes that the end of the world won't affect them personally, or anyone they know.
I will sit back and watch it all slowly decay and then eventually burn when the populace reaches critical mass
Where exactly do you think you'll be sitting comfortably when this occurs? Your apartment? Your house? I hope it's a well-stocked bomb shelter with its own independent water supply, gasoline-powered generator and you have enough supplies to last you for the rest of your life where you don't have to depend upon what civilization has to offer you. And I hope you bought enough guns and ammo to defend it, and the skills to use them.
Otherwise your comfortable chair is going to be pulled out from under you pretty quick. The lights will go out and your computer won't turn on so you can't post more of your pathetic incel screeds. The food in your refrigerator is going to spoil, and your local grocery store was looted. People are going to try to break into your house to take your stuff and murder you, unless you're prepared to flee the cities into the countryside, in which case you'll be in competition with millions of others who had the same idea. Which means you can die in any countless other ways or you can learn to trust and cooperate with your fellow human beings who you despise in order to ride out the chaos you so desire. But since you spent most of your adult life expressing hatred of normal functional people you quickly lose favor in the group and they exile you in disgust after they catch you trying to force your way on a 5 day old female corpse they found on the road. Either that or they put a bullet in your leg and leave you tied to a tree to bleed out after you were caught stealing food or trying to rape a 'Stacy' in the group.
the societal bucket cannot hold any more droplets of degeneracy.
Look who's talking. That's ironic as you'll probably be the one who has the least useful skills and be the first to be sacrificed for the greater good in such a scenario. You ain't going to be Immortan Joe, the King of the Wasterland. You won't be one of his top men or even one of Immortan Joe's henchmen. You'll be a corpse adorning Immortan Joe's fortress.
Maybe, just maybe you'll get lucky and some tough raider takes pity on you and makes you his sex slave. At least you'll be fed and won't be an incel anymore, though your anus might complain.
Or you could do the right thing and just off your self when things get this bad and remove yourself from the world of the future since you believe humanity to be a cancer upon it.
In none of these scenarios, do you get to "sit back and watch it all." You'll be in the thick of it pretty quick.
