"Open borders" is a nice way of saying "wealth redistribution".
I am for open borders if all countries do it. I am opposed to open borders if not all countries do it.
I know that foreign nationals may only stay in Mexico 182 days of the calendar year (6 months minus a day). There are whole communities of U.S. citizens in Mexico taking advantage of the warmer weather and lower cost of living. They are not a burden to the Mexican taxpayers and contribute to local economy. So, good on both sides of the ledger. We only hear about one side of the ledger from either side of the argument in the U.S.
Sure, criminal aliens contribute some money to the local economy in the U.S. and pay some taxes. However, the amount that is contributed is less than the cost of tax payer funded government services used by criminal aliens. Then take into consideration the human impact. U.S. citizens are harmed or killed by criminal aliens. Sure, U.S. citizens harm and kill each other, but there are crimes that could have been prevented if the U.S. just enforced immigration laws.
We have arguments over low and stagnant wages in the U.S. which fuels the drive for raising the minimum wage. Minimum wage only applies to companies and businesses who hire U.S. citizens or those with a right to work in the U.S. Criminal aliens flooding the U.S. have made it near impossible for U.S. citizens in the trades and construction to earn a living. Why pay a skilled union carpenter $35.00 and hour when their is a never ending supply of people who will do it for $10.00, cash under the table, coming over the border illegally on a daily basis?
People are fleeing their nation of origin to come to the U.S. due to rampant violence. All they are doing is contributing to those who are carrying out the violence. Mexican drug cartels use these people fleeing their country for the U.S. because it makes them money. The U.S. would be better off sending cruise ships down to Central America to pick up these refugees and bring them directly to the U.S., bypassing Mexico all together. This would reduce the drug mules and human trafficking into the U.S. which in turn would cut into the profits of drug cartels.
