Housing, startups, art, cars, watches...pretty much everything collectible or rare has seen its value skyrocket since the great recession.

The big pool of money has been sloshing between asset classes for a while now, but it doesn’t get reflected in inflation metrics.

I think this is a combination of low interest rates making the opportunity cost of owning collectibles much lower and rising inequality driving up the purchasing power of collectors.

Well houses have gone up, but the price of housing (rent) have only gone up a bit.(except for certain markets driven by regulation and fundamentals)

If the government increased interest rates until inflation was zero unemployment would be twice what it is right now. And that seems like a high cost to pay for a neutral monetary base.

Inflation is an average. Sure, you can disagree on how to compute the average (what gets more weight) but then it gets pretty subjective and then the question is: too high compared to what?
