I have a ONE step solution to self-deport ALL illegals (including those who flew in via airports). It will cost nothing to tax payers. It will not need armies of cops to search and arrest illegals. It will not need gargantual holding cells for 11-30 million illegals.
Step 1...pass a law which requires 1 year MANDATED PRISON term for each illegals found working in any outfit, for the CEO. No fines, because corporations will pay fines. But no CEO will like being in prison even for 1 day and night, with rapists, murderers, armed robbers, child molesters, and dope dealers.
No further steps necessary. The only problem will be shortage of seats on flights to Mexico City.
I don’t know where you live but I live on the front lines of this illegal mess and the overwhelming majority of them do not work for major corps like you are talking about. They work for small to medium companies and corps. that are family owned or by a small group of investors. Companies that cannot afford 10k per illegal employee and will rid themselves of them in a heat beat rather than get hit with the fines as well as getting on the federal radar.
No, the Steve Jobs, Bill Gates, and CEO’s of GM and Ford are not going to hire these folks and risk the political consequences.
Regardless, self deportation can be attained without an army of agents on the streets looking for wetbacks.
