Rents go up when people can afford higher rents. Consumers take out loans and save less when unemployment is low and they feel safe in their job prospects. Inflation was below healthy rates for a number of years, and is now where the Fed likes it. Wages aren't booming, but they're up, and up more than inflation.
Chapter 11s were at the same level in 2011 -- were you predicting a recession then too?
There are also reasons to be optimistic, for example, US corporate earnings are way up -- 2018 is up 20% over 2016 alone -- that's huge.

I think that the article is right: while the US seems very healthy, there are lots of international issues that could form the next recession (China specifically).
