Facebook CEO Mark Zuckerberg, along with executives of other successful US enterprises such as Apple, Google, Microsoft and Uber, has voiced concern about and opposition to the executive orders issued by US President Donald Trump since taking office.

In a Facebook post, Zuckerberg said that he is "concerned about the impact of the recent executive orders", adding that "we should also keep our doors open to refugees and those who need help". Zuckerberg's remarks are the first time he has openly criticized government policy.

Trump's policy of employing US citizens is superficially helpful to expanding US employment, but it is of no help to innovative enterprises who utilize talent from all over the world, which has been a source of endless vitality for them.

So Trump's ban on immigrants, if implemented, will fundamentally shake the foundation for the continued prosperity of these US behemoths. Shortly after the ban was issued, Apple voiced opposition and took measures to help affected Apple employees. For high-tech companies such as Apple, their deep-rooted corporate cultures of openness and inclusiveness are incompatible with Trump's "closed-door" moves made on the pretext of "national safety". They well know that the building of any border wall with Mexico will make the United States neither safer nor great again, but only isolate it from the rest of the world.

The US itself is a country of immigrants and its prosperity and powerfulness are largely attributed to its receptive mind and its incorporation of diversified and advanced cultures and talents. For such high-tech companies as Facebook and Apple that set no boundaries for staff employment, how can they sustain their past glory under Trump's new policy?

Compared with Zuckerberg and his peers, Trump has a narrow and limited vision. Without global talents and markets, US enterprises will not be great, and this is also true of the US.
