>A major boom takes more than just stimulus from the government, otherwise, they'd just constantly be printing money.

I disagree. Massive, massive investment in beneficial projects is what causes booms. The last great booms we saw in the States were both the result of massive public investment during and after World War II. This gave us large scale American industrial manufacturing boom of the 40s/50s/60s, and the research funded in 60s/70s/80s, would go on to produce Silicon Valley in the 90s and 2000s.

Its helpful to think about where money comes from. And what can be done with it. Private firms ripping off consumers doesn't generate anything at scale. Massive public investment, historically speaking, does.
