I am not so sure. We are due one soon, it has been almost a decade since the last, and we tend to have one every decade or so.
Also, we are now 114 (at the end of Nov) of straight economic expansion, the 2nd longest period in the history of our country and just a tad than a half a year from setting the record.
Our system was built to fail on a regular basis, so we will have another period of such sooner rather than later.
If you have some spare time I suggest your read this book on the subject...

All of the indicators are the bull market is ending.
Also every Republican tax cut is followed with a huge increase in government spending and a stock market crash. Trump's economic advisors have been told that when the US recession comes, it will be much deeper than other countries because of the combined effect of the high deficit and increased interest on the national debt.
Normally in a recession, you cut taxes or increase spending to "prime the pump", or some combination thereof. Because of Trump's tax cuts and huge deficit there is nothing to cut, and the deficit is already dangerously high and can't be increased. So when Trump's recession lands, it's going to be longer and deeper in the US than in other Western democracies. Trump has been told all of this, I'm sure, but he's banking on the worst effects of his policies not landing until after 2020. When he's safely re-elected.
The venal greed and destructiveness of this man is not to be under estimated.
