It doesn't take much to go from financially comfortable to feeling the pinch. So for the people who were already feeling the pinch (and there were a lot of people in this cagegory) there's nowhere else to go but feeling like it's a financial crisis.
My DH and I have slightly higher than average salaries, we have a DD (age 2) and fortunately thanks to my work, we have minimal childcare costs while I still receive the equivalent of a full time salary. We were previously financially comfortable with great savings potential each month, our savings margin has all but vanished. Our savings are dwindling to pay for the holidays/events we'd already committed to over the past few years (rearranged from covid) and we've cut right back on food.
Our petrol costs have doubled, we spent more on petrol last month to get to work than we did on food. If I didn't work from home 4 days a week we would have to cut back even more.
Basically, we are a couple on higher than average salaries, living in a cheap part of the country (so our mortgage isn't too high), with minimal childcare costs, work from home as an option for me to reduce petrol costs and we're still feeling the pinch. There will be so many people throughout the country who are on worse salaries, high rent/mortgages, high childcare costs, etc. Just one rise can tip them over the edge, we are lucky that we have luxuries that we can cut out if need be, but what do you cut out if all those luxuries have already gone.
That's why it's a crisis, because if you can't cope on the average salary, what hope have you really got?
