Foreign workers are a great benefit to the economy. However, past a certain point, foreign (non-resident) ownership of real estate doesn't provide much benefit to the local economy and can easily push prices up to the point where housing is unaffordable for locals, due to the influx of foreign speculators. Chinese ownership in the Bay Area and Russian ownership in London are two current examples.

As well as Venezuelan ownership in South Florida.

The complaint is that the people don't live there, and therefore don't contribute to the neighborhood. See the recent article about how Vancouver is dying for more info.

Because immigrants actually live here. it is isn't about foreigners, it is about absentees.

And that fact that when a billionaire leaves their home country, it is often for shady reasons, not innocent enduring persecution or suffering.

And also, jobs are given, not taken. So if they're going to unqualified people (whether local or foreign), the person taking the job is never to blame. They're just trying to improve their life situation, like anyone else.

No one gives a job to an unqualified person, not for long. (Maybe a nepotistic payroll handout to a friend, but not a job. A job only exists because the worker generates value)
