Once more, direstraits, you widen the exit flaps of your ideological tent to send forth a reply that avoids the core issue under discussion, namely which, if any, party conspires to import immigrant adults or children to allegedly be used as "slaves" or illegal child labor? Have the enforcement arms of state and federal labor departments even identified significant instances of illegal immigrant child labor or "slavery"? Have significant occurrences of actual "slavery" of adults or illegal immigrant child labor been documented anywhere? Maybe, but you have offered no proof of such.
"It is estimated that 17,000 to 19,0001 foreign nationals are trafficked into the United States each year. Trafficking is the recruitment and possible transport of persons within or across boundaries by force, fraud, or deception for the purpose of exploiting them economically."
Human trafficking is the modern term for slavery. What do you think would have happened to those 7500 children if ICE hadn't taken them into custody?
