If your family didn’t leave the war torn country you would’ve been screwed.
The same thing with the undocumented immigrant managing to get into the country.
Same as our cleaner. She illegally immigrated into Mexico first, but realized how racist Mexicans were against Central Americans, so she decided to work her way so that she could get into the US. This isn't luck, it's hard work. She didn't accidentally find herself in the US.
Your cleaner lady is such a silly example. If she was deported would you say she didn’t work hard enough to prevent it? Lol
And even if they did work hard your situation is entirely luck regardless since well, you didn’t help them escape with your hard work, yet you benefited.
