Government spending is not the root cause. If that was the case, we would have seen inflation much sooner, since we’ve been in the era of quantitative easing ever since 2008. The fed was starting to raise interest rates even before covid because the post-2008 recovery was turning into an expansion; we are still in that expansion phase, and covid fucked up our supply chains which kick started the inflation that would have accompanied the expansion regardless, but would have been easier to control in normal times.
