A nice, armed, HUGE, wall would end that lucrative drug smuggling route...
Two walls several miles apart to double our chances...would be nice.
If it was only a question of drug routes, that could be resolved overnight without a fence if the will were there on both sides of the border. But to maintain open borders for the new slave class, the powers that be will downplay the drug routes and amuse the people with the Mexican Hat Dance on the Senate floor, leaving the border problem on the back burner.
In addition, if the PTB make more money on the drug trade than they do on the alien worker program, the 'doing the jobs that Americans won't do' ploy covers what's happening behind the curtain or under the table where the real action is. In which case, the border never be secured -- fence or not.
IMO.

If they can't even keep drugs out of prisons a fence isn't going to stop the flow. They'll dig more tunnels, use sea routes, planes, and do like they have been doing all along through border check points where drugs come over in small vehicles or thousands of pounds at a time in large trucks. Most of the tonnage of drugs coming over is probably coming through border checkpoints, either with border security on the take or just by hiding it in loads and taking the chance that it won't be one of the few loads searched. Sometimes the truck drivers probably don't even know it's hidden in the loads they've picked up. These trucks are carrying far bigger loads than small vehicles and certainly backpacking illegals could ever carry. A fence would cut down a lot on the number of illegal aliens crossing the border, but it won't stop the flow of drugs. There is too much money to be made getting relatively small loads across the border for something like a fence to stop it.
