Whoa! Progressives can't scream for a $15 an hour minimum wage and then demand illegal cheap labor to keep wages down for low paying jobs. You want decent wages - ensure illegal labor isn't available.
I am not screaming for anything, I am just pointing out to you what the consequences of your wishes will be. Are you prepared to pay more for your products?
I believe putting more revenue in a person's pocket is a better solution to poverty than more welfare. In fact there have been studies that indicate welfare programs often extend the time someone is poor. Even the left leaning Brookings Institute admits this.
I think free and fair markets with minimal government interference are much more likely to result in someone being lifted out of poverty than is having an open border policy.
I ask again: Are you prepared to pay more for your food?
