The business cycle very rarely goes more than a decade without a recession. I say rarely because I haven't looked at recessions prior to 1920. But here; 1920, 1929, 1937, 1945, 1948, 1958, 1960, 1969, 1973, 1979, 1982, 1990, 2000, 2008, (?).
You'll notice that our last recession ended in 2010. It's highly unlikely that President Trump will not weather a recession by that period. Possible, but very unlikely.
I think it depends whether the length of growth increases the chance of a recession. Otherwise, this might be faulty logic, akin to assuming that a coin coming up heads many times in a row increases the chance that it will come up tails soon, when it doesn't.
There may be correlations between the chance of recession and the length of growth, but do we really know enough about what causes recessions to assume one is very likely in the next few years, beyond simply noticing the duration since the last recession?
