1.It's not solely about constitutionality, it's also about human rights.
that's because the mexican law doesn't really target people based on the way they look.
3. This sounds awful, but I really hope republican states fall on their faces after the cost of production and hence the price of domestic goods rice, tourism plummets, and their gdp falls, as a result of lack of illegal immigrants.
Xenophobia seems to be a concept that applies to their basic principles. It even seems to cloud their judgement: I mean, either people that think like this have had no recollection of what they learned in school or they were never taught economics and US history.
The US was built with immigrants, may I remind you all. And these immigrants were NOT legal. They all came in waves, Irish, German, Poles, Italian, Russian, etc.
Also, do you not see the economic benefit of this? First of all, because of the mere fact that they are illegal, they aren't payed minimum wage and so the cost of production is less, hence the final good is cheaper. Second of all, these people contribute more to public coffers in taxes than they cost in social services. Furthermore they contribute to the economy through their spending and consumption of goods and services.
Lastly, get over yourselves, immigrants don't want citizenship and they don't want to live in America all their lives. If they established some sort of work permit for people who want to work in the US, they'd go for a couple months, work and go back to their home country, maybe even be able to do this yearly by paying a fee to renew their permit. Moreover, they'd be subject to submit tax returns.
