'Tis the season to worry about the US economy

Editor's note: All major stock markets in the United States plunged before Christmas Day. Columnist Niutanqin comments in a post:

The once robust performance of the US stock markets used to be the pride of the current US administration, while the other economies' bearish stock markets have long been quoted as evidence of the success of the trade war it initiated.

But it is not a surprise that the US stock markets have finally slipped into bear market territory, given the US administration's unilateral and protectionist approach to the economy and trade.
