Huh? Literally everybody grasps this. This is the most widely parroted mainstream narrative about the economy right now on the internet.
Hell, you can't throw a rock at the Wall Street Journal (conservative) or the New York Times (liberal) without hitting a sentence that mentions wealth inequality brought on by fed policy. For further evidence, your comment has been upvoted to the top because everybody on HN believes the same thing as you.
Have you ever examined the idea that it could be you who lacks education? Have you thought about what the economy would look like right now if there had been no accommodative monetary policy from the Federal Reserve for the last 10 years?
You're angry because it feels like everybody is getting rich and you aren't. What you don't understand is that bull markets are always temporary. This stuff moves in cycles.
Sky high valuations on financial assets might be making rich people SEEM ridiculously rich right now, but this is not a permanent state of being. The companies and assets they own all exist in the real world and will eventually have to back up their valuations with real earnings.
The minute inflation starts creeping up, the federal reserve will have to increase interest rates and cut off the money printer. In an instant, wealth inequality will start shifting the other direction, and valuations will fall.
