Deflation tends to trigger massive layoffs since revenue drops and investment becomes a worse option than saving.

Everyone always hopes that economic downturns will affect everyone but them specifically, but it really doesn't work that way.

The article states: “Deflation is bad for the economy because consumers and companies may put off purchases or investments in anticipation of prices falling further. That in turn could further slow the economy, and create a vicious cycle.” China has a robust export business, let’s say you wanted a toaster to buy, you don’t need it you just want it, and this month it’s $12, but you remember seeing it for $15 last month and $21 the month before. So you wait and next month it’s $10. Now since you aren’t in a hurry to get this item why not wait and see how low it goes? Meanwhile Mr toaster salesman’s pulling his hair out because he can’t slash prices to get rid of this inventory fast enough. Or something like that. Now the Chinese government can do several things to go back into the inflation level, one of which is just print money. They also say in the article that they would rather see prices rise naturally and they believe that’s what will happen.

Because if it moves too fast everyone holds their money anticipating it'll get even lower, leading to less revenue, leading to belt tightening, leading to people holding their money even more tightly because they lost their income, on and on in a vicious cycle.

A lot of the economy only exists because of the idea that people are going to buy more than they necessarily need, for a wide range of reasons of enjoyment or personal project or as gifts for family and friends, so if people stop doing that for whatever reason, economy no have good time.

It means you logically should save instead of spend Very easy death spiral when everyone is saving instead of spending.

Because business bought too much avocado toast and don't have any savings. Every market fluctuation means they have to adjust overhead. First overhead to adjust is almost always Operation expenses ie labor.

It should be pointed out that the incentive for saving as opposed to spending also applies to businesses and labor, which means they'll slash jobs.

After all, why continue to pay you when the company can just wait half a year and then hire someone new for significantly less?

I doubt it's even bad, or at least not as bad as it's made out to be. People have already demonstrated that they aren't going to choose to lower their standard of living today in favor of tomorrow. Technology is already deflationary and people keep buying phones and computers and TV's even though those get better/faster/bigger/cheaper every year.
