"the Reagan amnesty didn't do that"
Really ..?? Then what did it do ..??
The differences between the Reagan and Bush plans aren't all that great. The Reagan plan legalized a greater percentage of illegal aliens than the Bush plan would do (at least as proposed), but the Bush plan appears likely to legalize greater numbers of illegal aliens overall. There are also some differences in the fees and the periods of time going from one status to another, but the mechanics of the Bush proposal are very similar to what occurred under President Reagan.
