It can happen for any reason (tariffs, coronoavirus, debt, etc) but it will probably happen. Our present society cannot continue as is, we simply consume too much. At some point we will run out of cheap raw materials, which is when most things will have to be made from reclaimed or salvage materials that require more labor to make useful. This is already happening with steel; free trade may have allowed cheap Chinese steep to kill Bethlehem Steel but it only caused Nucor Steel (who uses scrap as a base instead of ore) to rise from it's ashes. The person who oversaw this, Wilbur Ross, is now our Commerce Secretary.
The same applies to computers. Today there's a labor surplus in the programming market, causing lots of useless apps, hacking, bad software and a cottage industry when it all used to be inside AT&T. This will inevitably change for any reason I've listed (and ones I haven't or ones that society can't conceive of yet).
