The US should give back the land it wrongfully stole from Mexico during the Mexican War. That land is rightfully Mexico’s, and all profits gotten from gold and the California economy belong to Mexico. The USA should pay TRILLIONS in REPARATIONS! And a PUBLIC apology should be given by SHRUB! And then we wouldn’t have my Mexican Brothers dying in trucks in Texas, another rightful property of MEXICO! Whitey would be dying to GET INTO US!
USA OUT OF EVERYWHERE!!!
MY EYES!!!
US V RE!!!
Seriously though: you could make an arguable case for some people who’s ancestors are now part of the U.S. wrongfully taking a great deal of land. Reality is, though, it’s never going to happen.
And will the Mexicans then promptly had over the land and wealth to the Native Americans from whom they stole it originally?
Were you trying to embed the Mexican flag colors in your OP? Better luck next time.
First, read and follow the directions for all medication.
Second, which group of people are you representing?
Olmeca
Teotihuacan
Maya
Tolteca
Aztecs
Spanish Conquistadors
Afro-Mexicans
Pick one and run with it.
Third, America is prosperous because of a successful culture. All the tools you need to be successful exist in Mexico. We didn’t steel your self sufficiency.
Fourth, don’t let your despair ruin your life. If you have the time to surf the net, you have the time to spend with friends. If you’re depressed, SEE A DOCTOR. That’s what they’re there for.
I’ve been to Texas. Trust me, you don’t want it back. 
I am so grapeful for this debate.
As soon as Mexico gives back its land to the Aztecs.
Gee, I didn’t know the US had robble-robbled any land from Mexico…

I doubt Mexico could survive acquiring California. The Trillions in Reparations wouldn’t even begin to bankroll there political idiocy.
