then the story changes into 'their economic migrants seeking to get rich off American taxpayers
That's not what I said. They want to go and work in America, because it's the best economic option in their region. But you're suggesting the taxpayer should foot the bill for their stay in hotels or whatever while they are processed having entered the country illegally. That's crazy.

They should be detained while they are processed, and any children they brought along with them should be put into appropriate care.
