When you find a kid separated from his parents, you send him back home home to his parents, not to some camp or school thousands of miles away in a different state wher he can stay without his parents.
You're right. So their solution will be to bring the parents here.
A lot of the parents are already here illegally and these kids are being reunited with them. That blows the whole “running away from gang wars and unrest in Central America” argument out of the water. They are coming here because they think they will be treated like dreamers and their parents will be allowed to stay under the administration policy of not deporting families.
