"A bubble is a problem almost by definition."
Define a "bubble". Capitalism, a debt based driven industrialized society (high capital requirements and pre financing for the production of goods) is a running bubble. You always have to create a bigger one. And that "most money was printed the last 10 years" is just a consequence of this.

When overvaluation falls into a self-reinforcing spiral. Of course overvaluation is only obvious in retrospect. But our industrialised society has delivered a lot of very real quality-of-life improvements, so I think the value is real.
You can also increase the velocity of money; the economy is the product of the supply and the velocity.
