Here is a short explanation of what the book is.
Children are separated from parents by the government not only at the border.
State government has nearly 400,000 children at any given time separated from their biological parents and subjected to abuse, exposure to adult dangerous psychotropic medications, medical experimentation - and, ultimately, permanent separation from their parents, adoption out of foster care, for which CPS gets thousands of dollars per head of the child from federal incentive money, courtesy of federal legislation passed under President William Clinton.
I wrote about the legislation in 2014 here, when Barrack Obama was President. Nothing changed since then - to the better.
Since the money incentive law is federal, all states have adopted similar CPS laws to satisfy federal conditions to get the incentive money.
Thus, the nightmare parents across the United States are experiencing is similar.
