Those that do not, and can make it here under those conditions will make fine Americans.

Your second sentence contradicts your first, in that you concede that they won't all leave.
Your second sentence also contradicts the law, in that Illegals can never make "fine Americans." They can never be Americans at all. In fact, they can never legally earn a dime, because you said in your Solution Pt. I that you would "Prosecute US employers that knowingly hire illegals."
Unless there's another aspect of your solution you haven't mentioned?
In addition, by letting Illegals stay at their own discretion, you never remove the biggest of all incentives for more to come here in violation of our laws...
Because they can and we let them.
Doesn't matter how good your other suggestions are: No deportations = no solution.
