Really? So I just got a 'raise' at work from deflation, somehow that is demotivating?
Here's the fallacy -- how long do you think that "raise" will last in a persistent deflationary economy? Prices are going down, because monetary value is going up. That means corporate revenues go down. People with large amounts of money invest much less, because an investment would have to have a LARGE rate of return to actually be worthwhile... otherwise, you just hide your money under your mattress.
So, fewer investors, decreasing prices... corporate revenues go down. And somehow you think get to keep you "raise" at your current salary in deflated dollars?? Fat chance. Eventually, they need to start decreasing your salary -- probably even more than to keep "pace" with deflation, because of the decreased revenues. Or they just start laying people off.
But that's only the tip of the iceberg. Why would you buy property in a deflationary economy, when it is likely to be a depreciating asset? Loans become nearly impossible to justify -- banks would still have to charge interest on them to justify them, which means you're throwing money at a depreciating asset, while the principal of your loan and your payment sizes effectively grow due to deflation. And given the depreciating value of assets, banks are likely to require additional insurance fees in case of default (a lot more than they have on risky mortgages today).
People stop trying to get loans to open new businesses. Investors stop financing them, unless it's basically a "sure thing," since they can "make money" just stashing their cash away. People stop taking out loans for basic things like real estate and houses.
"But," you say, "Maybe that's a good thing. Maybe people should learn to save up more before buying a large purchase." Okay, except who do they rent from in the meantime if they don't take out a mortgage on a house? The people owning rental property face the same difficulties in maintaining a rationale for owning it. If it's decreasing in value, along with other goods, rents will eventually be driven down too (along with the decreasing salaries). Why invest in maintaining property? -- it's just throwing money at a continuously depreciating asset.
If you're a landlord in such an economy, the best strategy is probably to dump your property now and get more money out of it while you still can before its value decreases further.
And we can go on and on. People hoarding cash and dumping most other investments leads to economic stagnation, then worse. Eventually this results in a deflationary "spiral" and the economy tanks.
Oh sure, throughout all of this SOME people will still invest and spend money, but it becomes increasingly hard to justify.
People who support deflation generally never think through even the basic next steps in their logic. They just think they'll magically have "higher salaries" coming from somewhere to spend on cheaper goods. That doesn't happen in real economies. The only people steady deflation is good for are people who have giant money bins already. For everybody else, you'd be much better off with the 1-2% mild inflation and actually having a more active economy.
