My thoughts exactly!

I noticed the words cycle chart in a link to Mosler's, so I went looking. This graph, from John Burns Real Estate Consulting, LLC:

I guess you could say that economic growth has to end in recession sometime, so the longer growth continues the more likely recession becomes. But if you look at it the way John Taylor did in 2016, growth didn't even start yet.
