this whole "we want open borders" is so fucking dumb. Again, speaking as a formerly undocumented immigrant, and having conversations with my group, no one supports this shit.
contrary to what most of the racists would have you believe, the vast majority of Mexicans would rather live in Mexico than to have to move to an entire new country where they don't understand the language, don't have their food, leave their families behind, etc. The vast majority of my extended family still lives in Mexico and would never even consider moving to the US, much less illegally.
My family did not immigrate because they were refugees or fleeing from natural disasters or war. It was an economic situation and the hope for a better life (like the mast majority of Europeans who immigrated to this country).
A good first step would be to create a temporary worker's program. You're given a SS number and pay into FICA, SS, and Medicare, and can work a maximum of 6 months in the country. You're allowed to travel back and forth to visit your family in Mexico / Central America whatever. You must stay out of legal trouble or your pass is revoked. Said worker contributes to our economy, paying taxes, and sends money back to his family. THen lives the other 6 months in his own country. After 10 years, you qualify for citizenship along with your immediate family.
For those undocumented folks that have been here 10+ years, put them on a path to citizenship. Ensure they've paid taxes (my parents did so even though they were undocumented), you pay a fine, and get on a path to citizenship.
But no, the GOP and racists would never go for anything so sensible, because it's racism that's driving these policies at its core.
