Sanctuary cities have run loose for long enough. They were incentivized under the Obama administration and now under the Trump administration he is going to ensure they are as minimal as possible. The town of Dearborn, Michigan is one of those cities. A city overrun by immigrants, with an influx in mosques, churches, and Islamic stores.
A lot of these political refugees are on welfare and using entitlement benefits. Meaning the American taxpayers are paying for their lifestyle.
The United States is already struggling with inadequate healthcare, a declining job market, stagnating businesses struggling to survive and an increasing incidence of homelessness. The issue of over population due to liberal immigration policies is the straw that will break the camels back.
The purpose of allowing people the privilege of moving to the United States is to allow them to begin a new life and to integrate within the new society. The purpose is not to allow people to simply set up shop here and reinvent what they had back home. If that is what they want then what was the purpose of them coming to begin with? They mine as well have never emigrated here to begin with.
