You are correct when you say that Mexico is not Cuba.
But you have the refugees reversed.
The Cubans who fled Castro were heavily laced with business people, professionals and intellectuals who would be the prime targets of any bloodthirsty Communist regime. They were running away from forced labor camps or execution at the gentle hands of “Che.”
The vast majority of ILLEGAL Mexican aliens coming here now are walking detritus. They are people with no skills and no wealth who are not running away from anything, they are running *TO* the welfare state.
Oh - they are also heavily laced with MS13 and other varieties of gang bangers who view the US as fertile ground for selling drugs and “organizing.”
And yes - I do know a lot of folks from both groups (Cuban and Mexican.) And the Mexicans I know who are LEGAL immigrants and have real jobs hate the Alien Invasion more than we do.
All with the blessings of and lining the pockets of MANY MANY politicians, who see this as the best BOOM since the Gold Rush, can't get much better than that.
