Illegal Immigrration solutions

The two major solutions to illegal immigrations (amnesty and securing borders) both seem to be band-aids that don't address the causes of the problem. I think the fact that legal immigration is so hard is a huge factor in illegal immigration.

There is a plaque on the Statue of Liberty that says "Give me your tired, your poor/Your huddled masses yearning to breathe free" and before 1921 we didn't restrict the number of people who could immigrate but now we have an arbitrary limit per area.

We should first ensure that there are minimal hurdles to legal immigration. That will greatly reduce illegal immigration and allow us to focus our border security efforts on the real bad people. It will also give a great incentive to current illegal immigrants to go back and come through the legal path.
