There is nothing to sustain.I'm not saying you're opinion or feelings about immigration are invalid. I am just saying I disagree and don't see overwhelming evidence that the U.S. can sustain the current level. It's not just about the economics. It's also about stress on various communities.
I always laugh when people use this word.
"Sustain".
Even illegal immigrants do something to feed themselves.
And what communities exactly are feeling the stress?
What kind of stress?
Where?
Dog whistles are not justifications.
