This is so counter-productive because these border immigrant shelters fill an important niche working with government services. There is no government agency with the resources on the border to house all of the people who enter the country to legally seek asylum.
They have to stay somewhere while they are being processed before traveling on to the interior. They also need logistical support in making their way through both the legal system and the US transit system to get to their destination. Border shelters do all that, allowing the government to do its job.
