I haven’t put much effort into the topic but I keep thinking there must be a better way than a fence or trying to catch them once they have made their way 20 miles or more inside the border.
Can’t this be broken down in to a simple exercise in controlling a “black market”? It seems to me that if there were no minimum wage, welfare, free schooling, and no guaranteed health care the immigration problem would go away. Employers in this country have to pay a “tax” for domestic, legal, labor. It’s just like a tax on anything else. As soon as the tax rate on a marketable product goes above about 15% the government ends up creating a black market for the product.
In other words I suspect the government could solve the immigration crisis by repealing laws and spending less money rather than trying to come up with more complex government solutions to a problem they created to begin with.
