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.
You are the only one who sees how dangerous deflation is. Most people will choose scenario A immediately because they have a very short-sighted view and don't have a clear understanding of how the economy works.
Commodity prices falling too far will be a real nightmare for businesses, while businesses are where products are created and where jobs are created for people. If commodity prices fall, it will lead to losses and thereby mass bankruptcy and widespread unemployment, which destabilizes the entire world economy. That is also the reason why the Fed always seeks to keep inflation below 2% and the economy achieves strong growth.
