Its close. The last estimate by the Border Patrol was approximately 20%, but I believe it to be higher.

No. First off, it would be impossible to build a 30 high guarded wall along the entire southern border. Second, if its guarded, why build the wall, just have the people. It cost less. The maintenance cost of the wall would be astronomical.

Pretty deep.
If you wish to stop the flow of illegals, then take away all welfare, jail anyone who hires them and take their businesses, and help build Mexicos economy.
If there is not job or benefit in coming to the US, and the Mexican economy is good, they wont come.
