data doesn't lie and the data shows them being a success.
No but it can be interpreted in the completely wrong way when you forget about the supplementary data driving the numbers you look at, as evidenced by all the treads in this post calling out that even though the stock market numbers look good that's not really painting the whole picture of our economy. A boost in using services like online shopping delivery and what not could also signify people have significantly less time, working multiple jobs maybe to make ends meet and this is the only way to get groceries. That doesn't mean they feel the service is great just nessacity is driving its adoption. Couple that knowledge with a low unemployment rate and those data trends can start to paint a different picture than you initially thought.
The world does not stop because prices fall, people still have needs and wants. Just because money will be worth more down the line does not mean people will suddenly stop impulse buying or purchasing necessities. It means superfluous spending would drop. Billionaires would loose enormous wealth as people stop playing with futures, it would not kill an economy it would kill the wealth gap and wealth classes. The biggest problem is the US sells its debt but in a deflationary time said debt loses value not gains it. But even that you can reverse to still encourage growth. The biggest "issue" is the common man drives the economy in a deflationary period by purchasing nessacities instead of bullshit waste to drive growth numbers.
