I don't believe it'll require 20%, but they absolutely did let inflation get away from them, and their "relief" programs will make it worse. So if they don't get their heads out of their asses soon, we may have to crank it up into the high single digits. The problem with that is that it could trigger a lot of nasty surprises we've brewed up over the last two decades: explosive consumer and government debt, a housing bubble, and excessive and underfunded entitlements right as the baby boomers are retiring.
It's really quite appalling how much our government has let us down since the mid 2000s. I can never quite understand why the important issues to voters aren't the economic timebombs we've been constructing....
