You think we'd see a reduction in expenditures? Whether we're spending tax dollars on welfare or on border enforcement, UAVs, investigating employers, etc we're still spending tax dollars. Once that money starts flowing to the new pots, those pots will continue to grow.
Like I said during the last election- the only difference between Democrats and Republicans is who is getting the tax payer dollars.
You're right. As I stated in the other thread, we shouldn't be hindering humans freedom to travel and seek out a better life for themselves. We should have a process in place that allows unrestricted movement but still lures them here through legal means so that they become another cog in the machine and not just a taker.
