You don't understand the Reagan Amnesty either. It wasn't absolute, it also charged a fee, and if registration is your bugaboo, it's the Amnesty for you, because it registered a higher percentage of illegals than the Bush Amnesty would, since it's not employer based.
By the way, the Reagan Amnesty's citizenship mechanics were about the same as Bush's: temporary status, then green cards and five years of residence, and then citizenship. And, like the Reagan Amnesty, the Bush Amnesty would also raise immigration levels to accomodate legalized illegals.
Put up or shut up. What was the fee that you claim illegals had to pay under Reagan's Amnesty?
