This is one hell of a nice article setting precedent for what conservatives (in my view) are pulling their hair out over. So, if my tiny 20 y/o brain can wrap my head around this article, then America's current deficit spending with regards to it's GDP is relatively low? The author's point I derived being, "We have tons of room to start spending more." On this topic, this will sound like a stupid question, but there really isn't any serious issue with deficit spending here? Further, where the hell would that extra money be put toward? Lord knows there's lots of reformation and streamlining (looking no further than, but not limited to, healthcare) that could happen in the different facets of the system before throwing money at any industry willy-nilly.
