The fall will be bigger I feel. Even in the 80s not everyone had a car, certainly not multiple cars. Not many had phone lines let alone multiple lines with different mobiles. If you were lucky you might have Sky TV but reality was most didn't.
What about food? Seems like it was a simpler time, more home cooking and less eating out. Now folks have got used to paying £X over the whole vegetable price (as an example) to get say a bucket of corn cut into pieces and thrown in garlic butter for the microwave; or the plethora of other "fast" veg available.
I don't remember too much about the 80s, I do know we weren't poor but I still remember steak was a treat, take out was few and far between.
Now we have got used to all this "extra" parts of life which is great but it will be those "extras" that some will have to cut.
I can't help but feel there's a greater disparity of wages too. There's more people living side by side along economic lines than before. Resentment will drive some into petty crime (not just theft, perhaps silly stuff like scratching a car bonnet because that car is new).
All this will play out against a backdrop of social media, a lot of people will continue to "keep up appearances" at what cost to their mental health? Will some choose to go without groceries for the sake of keeping the internet bill paid?
There are families I know of who already juggle bills, where the parents don't eat every day to make sure the children can. I know of single adult homes who are trying already to eek out a meagre existence on cereal made with water, and a few biscuits. And that's now. If the country goes bust what happens to the benefits safety net? Will the country borrow (can it?) to try and support itself? What shadow will that cast on future generations? Worse will those who are sick and disabled who have already been getting a rum deal the past few years, how will they suffer?
The really scary thing is that the 80s recession has nothing on the Great Depression of the 1930s and there are many studies that have forecast a depression now could be infinitely worse than even the Great Depression.
I'm getting off my soapbox now because quite honestly I'm feeling a little bleak having thought of all the above.
