What people think living in a deflationary economy looks like: Groceries are 5% cheaper than last year.
What living in a deflationary economy is actually like: Nobody is spending money. Your hours are cut and you won't get a raise this year. Your income is down 25% compared to last year. You can't afford to buy anything. Businesses everywhere have to cut prices to compete for the dwindling number of customers.
Investment dries up. Job creation comes to a complete stop. 500 people competing for every job opening that comes up. Wages keep going down as a result. The uncertainty means that even people who still have a job are choosing to save as much as possible rather than spend.
Foreclosures rise, people lose their homes as the wealthy snap up the newly-freed housing stock at distressed prices. Car repossession rates skyrocket, causing a surge of used cars to enter the market, dragging down new car prices along with them. Automobile manufacturers start biting their nails as analysts project lower sales numbers and tighter margins, pushing most heavy industry into the red. Workforce cuts soon follow.
Credit default rates soar, leading to the first bank failures. National deposit insurance schemes soften the blow and prevent a full banking crisis, but deposit insurance rates start climbing, causing banks to raise fees and cut benefits.
The lower economic activity causes budget shortfalls in every city in the country. Poor tax growth forecasts force local councils to start cutting services. The first to go will be cultural events. Then the public transport cuts come. And then homeless services. Then eventually all departments except police, fire, water, and electricity get cut down to the bone, and then some. Maintenance on public buildings get slapped with 5- or even 10-year deferrals.
People are skipping meals to make ends meet. Produce rots on the shelves until grocers learn to order less. Lower crop prices push many small to medium farms into insolvency; larger corporate farms are better able to weather the storm. Groceries are 5% cheaper than last year.
