Deflation means a dollar tomorrow is always worth more than a dollar today meaning a rational person should strive to spend as little money today as possible. This eventually locks the entire economy up into a death spiral.
The reason for my skepticism is that even without deflation, a dollar tomorrow is usually worth more than a dollar today, yet tons of people* don't save or invest much/any of their money, even if they're able to.
* I'm speaking from the perspective of an American FWIW.
No, that’s deflation.
If you’re talking about investing, that’s different. The dollar is still worth less on its own. It just made extra dollars in the meantime.
The US economy had zero net inflation from 1800 to 1914. No death spiral.
The whole "2% is good for the economy" is propaganda to hide the fact that deficit spending causes inflation and is a tax on the economy.
I've heard that £1 was worth the same in 1914 as in 1614.
