You need to read a book called The Millionnaire Next Door. The "American Dream" is very much a real thing and it rarely involves luck or exploitation. At the time of the book's writing, 80% of millionnaires in the US were first generation millionnaires and a large part of them first generation American immigrants.

> Capitalism means a huge chunk of people literally have to be poor, other wise costs rise, inflation goes mental and capitalism fails.

Of course "poor" is a relative term and the standard of living for the poor continues to rise as new innovations, efficiencies, and wealth enter the market. A poor person can walk into any supermarket and buy food that would have been considered and absurd and extravagant luxury 100 years ago. They can buy cell phones that let them communicate with anybody in the world instantly. But yes, there will always be someone who has less than somebody else, but what does it really matter if everyone's standard of living is rising?
