Zero isn’t bad. I was explicitly talking about deflation above. The effects of deflation I explained above is not a myth, it is introductory macroeconomics.
Deflationary spirals have happened in the past, but they have stopped since we moved away from the gold standard and we can now intentionally inflate our currency to prevent deflation.
If you have a real business, you're still increasing value in the equation or breaking even. Deflation means you might have to lower wages, but your employees are still getting the same value paid. It means you might have to lower prices, but you're still getting the same value sold. It also means your costs are lowering, so as long as you have a value-adding business you will beat deflation. If not, then you shouldn't be in business.
In today's inflation economy, there are tons of tons of businesses that on paper make a profit, but in reality don't create value because that profit is worth less than the numbers tell. And what's worse: Individuals are becoming poorer and poorer without realizing it, because the nominal value of their pay check might be higher, though the value of the money is probably half of what it was 10 years ago.
And as individuals adapt their lifestyle and spending to circumstances we arrive at the ridiculous situation of today, where most young people after maybe a decade of working and advancing their careers still don't own a home, still don't have any children, and don't dream of splurging on luxurious hobbies.
Thank God there is a huge trend right now with workers of all "collars" saying "fuck it" and doing what they can to change companies, change careers, change cities and change countries to get as much as possible for themselves instead of continuing to be exploited.
This is not something economists disagree upon. All periods of any significant deflation anywhere and at any time were accompanied by economic recession or depression.
If it were just so simple that a “real business” could merely adjust everyone’s wage to balance the books when revenue drop, you would be the world’s most coveted CEO that could save any company.
It ain’t that simple. Businesses make capital expenditures. There’s also often a time gap between incurring costs and incurring revenue.
