And that's NOT a drain on the American economy????
IT IS IN FACT A TREMENDOUS BOON TO THE US
And here is why. Suppose all the working men in the US sent their children, wives and elderly to mexico and just worked at their job in the US. No more taxes for schools, medicare, social security, etc. and then you could sent one tenth that amount to support them in Mexico.
A working man probably needs 100,000 a year to keep a family in the US, but could do it on 40,000 if he shipped them off to Mexico and sent them money instead.
