I didn't agree with the Reagan Amnesty and am not too crazy about the one which is going to happen this time.

The Democrats want the votes and the Republicans want the workers.

A new amnesty will happen.  There will be no enthusiasm from either side to actually enforce the border.

So, yes, we will "do it again and again and again".  

That's politics.

The "Immigration Problem" will exist as long as the US limits immigration in any way, shape or form.  

Too many people will do almost anything to get in because the rest of the world seriously sucks compared to us.  The very bottom of our country is so superior to where so many of them are that the "Immigration Problem" is forever.
