I doubt it. There are huge amounts of people who would love to move here, given the chance. People who can't get a work visa for the EU, for example. Or even from the EU and are interested in cutting edge things. They don't care about politics, they just want to come and work.
I'd bet, even the people affected directly by the ban, if given the chance would accept, despite your assertion.
When I go to work or live in a diff country, the thought about immigration policies do not enter my mind aside from, can I get the visa.
I work as a consultant remotely, most of my customers are American companies. I've been paid a bit more than 1 million USD altogether in the last 4 years but haven't contributed back to the US through taxes. I also didn't contribute to the local economy there because I do not live there.
Once upon a time, I wanted to immigrate to the US but the immigration laws convinced me otherwise. I'm interested in cutting edge things but I found that I could easily work on them without being in the country.
This is just anecdotal and I don't know how many are like me but I do have quite a few friends in Europe who have the impression that the immigration process to the US is over complicated and reject trying to go there out of hand.
I'm sure there are cases like yours --and it's probably not a bad thing for the world economy and prosperity. There is a benefit to other nations becoming economically healthy, rather than suffering "brain drain" and having their brightest minds only go to already successful economies further contributing to declining conditions in those countries. We only need to look at the state Russia and South Africa are in and where they could be, if they retained their talent.
