Trolls? Sounds like YOU need to understand what QE is. From Wikipedia...
"Quantitative easing (QE) is a monetary policy whereby a central bank buys government bonds or other financial assets in order to inject money into the economy to expand economic activity."
Sounds pretty inflationary to me. Especially when they buy up illiquid mark to fantasy assets that nobody wants and unloads them on the taxpayer to foot the bill while their buddies get a wad of cash to redeploy, into the stock market as it turns out. How is that not inflationary exactly? Oh, the destruction of those bad assets? Yeah I suppose but the socialization of that across America hides that and what's left is pumped up asset prices that cause the average American to have to work even harder to save up to buy and get worse returns because the fed's buddies got in first and drove prices higher.
Have you happened to look at the price of assets since 2008 vs. the actual recovery of the economy? Have you seen that S&P earnings were flat to down for the past 4 years going into this crisis? Yet what's happened to stocks? That's right they've tripled since 2009. Go look at any piece of real estate now almost anywhere vs. 10-20 years go and tell me there's been no inflation.
I realize it's different everywhere but the idea that we've had "low inflation" over the last 10 years is completely laughable because the calculation removes the highest cost items. The fed has effectively destroyed any price discovery on any assets. It's taken increasingly larger amounts of QE to goose the fake economy. And now for its encore it has overreacted to save their buddies and decided to lower rates to zero and tell the world that it will never let assets fall. How in the world is that not inflationary when you're flooding the market with free money and enabling those at the top to buy up assets and run up prices?
Every single person that works to earn USD and saves USD should be livid and rioting in the streets for the theft that's been, and continues to occur.
Also, your example of Japan isn't apples to apples. The US has the world's reserve currency and can print as much of it as it wants, Japan does not. Japan is a nation of savers so getting them to spend is harder than a US citizen.
We may have short term deflation and that's what the fed is scared of but make no mistake about it what they've done is inflationary as they will well overshoot whatever deflationary impact any failures have. Hell, they've made it clear that's what they're gonna do.
