Yes I listened to PM and it was the most unsettling news broadcast I've heard for several months.
We won't get social collapse in 6 weeks but I do think we're in for a winter of discontent.
Looking at the world situation and the state of the environment I also think we are now tipping into long term societal decline and I'm quite happy that neither of my adult DC are planning children. I think things will be bad enough in their own lifetimes. There won't be any dramatic 'social collapse' event. For the most part, things will just slowly and inexorably get shitter over years and then decades.
I agree with PP that rioting depends largely on the weather so now we're into autumn there is less risk. But rioting also depends on is access to food and other vital necessities. It doesn't matter why the shelves are empty, if they are empty for a few days in a row then we should expect trouble, even if it's raining.
I don't like the sneery minimising of rioting on this thread. 2011 kicked off over not much at all and it was devastating for those of us living and working amongst it all. Everything was either boarded up or on fire, everywhere smelt of burning, everywhere felt like it could kick off again at the slightest provocation. Pretty much every city and big town in the UK was badly affected. In 2011, despite the very recent world financial crash and the introduction of 'austerity', we had the resources to contain the crisis and to rebuild high streets and businesses. I don't believe we could do that now if we were faced with a similar level of unrest. Completely boarded up high streets could easily be the new normal.
Keep a bit of an eye next week for the clocks changing / halloween / guy fawkes - that can be a bit frisky in a normal year. After that we're probably fine until January. Do your best to avoid running out of anything and have a plan for temporary loss of power, water etc. but don't be a wanker.
Meanwhile grab onto every scrap of joy life throws at you because you're alive now and you won't always be, whatever else happens.
