I know quite a few Vietnamese who floated on rafts in the South China Sea, a few dozen Cubans that came with nothing after the communist government took it all. I also know 30 or so illegal Mexicans who show up everyday for work and are doing well for themselves . None of these people spoke English. The Mexicans still don’t. One thing they have in common is that they are not afraid of working and work everyday if needed. The Cubans and Vietnamese people got good educations once they got to N America. North Americans generally have a poor work ethic and expect hand outs, the Mexicans actually laugh at how lazy Americans can be. My father and his 3 siblings were poorer than poor. All 4 of them became very rich by working hard and going to school at night. Hard schools too. The top engineering schools. It can be done. But most people are too lazy.
