I think the Americans have borrowed from their future to inject into the present in the form of the corporate tax cut. The conversation should be more on the huge rise in debt in this short term period and how growth will not compensate for it unless they can grow GDP at 5-6%. It really puts the whole thing on a more precarious position going forward now, because a slow down would be exponentially worse for the US.
I take all the articles with a grain of salt from any financial publications that stand to make a profit. Keep in mind that they make their money too in times of chaos. Ratings are generally higher during bear markets and of course one off events.
