Trump is merely an embarrassment to this country. Americans do not really need to know that their asshole president thinks that Merle Streep is a bad actress because she does not like his sorry ass. A decent president would say nothing at all if a celebrity criticises him. He is an egomaniac like the Evil Queen Gwendolyn who felt compelled to ask her mirror daily "Mirror, mirror on the wall, who is fairest of them all" in the fairytale Snow White, who then feels compelled to kill Snow White when the mirror proclaimed her the fairest of them all.
Trump is an egomaniacal asshole and a repulsive, pussygrabbing demagogue with a horrid inferiority complex, and he will always be one. Not a single intelligent American will boycott a Merle Streep film because of trump's asinine tweet. It is entirely possible for an actor to have all sorts of wacko opinions and still be an excellent actor. Take Marlon Brando, for example.
What his idiotic practice will do is cause instability in the stock market when he lambastes a company for producing stuff in Mexico or China or where ever. The DJIA is, in my opinion, overvalued because the premise is that Trump will cut taxes and/or regulations which will cause profits to soar. But change in taxes and taxes and regulations will come slowly, if at all, and will have less an impact than the market thinks. If Trump starts playing with the stock market as though it were his personal toy, it could cause a lot of harm.
