Liz, You make a lot of great points in your posts, about how our welfare system has been abused by many immigrants - legal and illegal.
This is not only recognized in the White House, but is the target of an extensively coordinated, “Whole of Government” effort.
White House Adviser Stephen Miller described the goal of the effort, to be to reduce “welfare seeking” among immigrants.
The vision of the Trump Administration, is to move our immigration system to one based on merit - with greater preference for those likely to contribute the most to our society (wealthier, better educated, healthy young adults, free of criminal histories).
The very first priority was to target the worst among the immigrant population - violent criminals and gang members. The current effort is another quality cut, systematically targeting the lowest performing economically (including most of the the outright negative performers, who are an unmitigated drag on our economy and finances).
This rule change, although major, is just one of many coming out this year (starting back around March, and expected to continue), seeking to take away the incentives from welfare seekers.
When my wife applied for a green card I had to certify that I woud be financially responsible for her for a period of years (5??). These turd world parasites it is said are costing us and our children approximately 60,000 per year, more for asylum seekers. What a fleecing we take. Insane government—facilitated by we the citizenry with our heads somewhere other than where they should be. We are all fools. Our children will suffer.
