Which of these economic situations would you prefer to find yourself in?
A- Your salary is stagnant but prices fall. Where this happens, your real purchasing power has increased. It's called constructive deflation. And even if your salary falls, but prices fall faster, you are still ahead.
B- Having your savings taxed 2%+ a year by inflation.

Situation A would be a nightmare for all business owners. Deflation is a predecessor of recession/depression and growing unemployment rates.
Even if you enjoy a growing purchasing power due to falling prices, you might end up losing your job and your monthly income.
I prefer situation B, 2% inflation is really low and I prefer low inflation over deflation. Any inflation above 2% or even above 5% would lead to a bad situation for me and for many employees.
Deflation is bad when governments have fiat currencies in place, as this means the economy is in such a bad shape that a collapse is imminent anyway.
But if the economy was based on the gold standard or something similar, which is the way the world economy worked for most of human history, then it will nowhere near as bad, as getting less for each unit sold can be compensated by a lower cost to manufacture it and selling more of it, which can be done as now more people can afford it due to the cheaper price of products.
