The US is full of opportunity and "chances". Just because you feel nobody has a chance does not make it so. Nothing is for free - you need to be willing to put the effort into making it happen.
The company I used to work for had the HQ in France, and there, all the devs doing the stressful mediocre pay grunt work, were all Mohamed and Ahmed immigrants from North Africa, while all the suit & tie managers with expensive haircuts doing nothing but have coffee and joke around for 4 hours/day, were native white French dudes.
I wish this was a meme though, but this is my anecdote from my time there.
