Borders are just imaginary lines drawn up by arrogant people. The Roman Empire had borders - where are they now? We all bleed red. What happened to the U.S. that allowed everyone who arrived to Ellis Island to become part of our country? We need to return to that -- anyone who wants to can come and stay here, period. Instead of $5Bn being used to build a wall, have it spent to hire workers to tear down the existing fencing and install permanent water and shelter stations on the border - to protect migrants from sunlight and provide first aid kits, etc.
If our elected officials had even an ounce of compassion, anyone who wants to be here would be allowed to and would be naturalized with no bureaucratic hurdles. Give them a year or two of SNAP, WIC, TANF, Medicaid, and Section 8 as applicable until they land on their feet. This is what a compassionate country would do. Incentivize employers to have supervisors that are fluent in both English and Spanish. Establish both English and Spanish, possibly others as official languages of the U.S. much like French and English are in Canada. Appropriate funding to provide free public translator social workers that are available in every county to assist new immigrants.
Abolish all attempts to restrict the flow of human beings from crossing some imaginary line. End the insanity.
Contraband is going to get in either way, whether it's brought in illegally or walked in through legal migrant means. That's a separate issue, but I'm in favor of legalizing all forms of recreational drugs and taxing them, with common sense regulations as to labelling etc. Price them cheaply so that violent organizations cannot compete because their products will be inferior and more expensive.
If some huge wall is built, then tunnels will be built under it to facilitate smuggling and 'coyote' migrant services. It's all for nought.
