There are multiple ways to survive in the United States.
Illicit or legally.
Illicit is short term money with long term consequence...doing it the "Street" way (non legal hustle) - which is definitely not worth the ramifications. Now if you sending them kids to private school/colleges to get ahead legally thats another story, but short term stunting is short lived if its illicit.
Most successes are based on some aggressive strategy, but must of which is result is legal. Heck, corporations get away with certain practices because its a corporation.
Whites only make up approximately 7 - 9% of the world population. They are not the widely population. Even some say whites mutated by blacks including during the ice age, where they could not produce melanin/color. Also a black couple could make a white baby/albino, and blacks come in 33 variation of colors.
However in America, there is a culture, the work culture, at various levels. Poor/lower/middle/upper/uber uber/ultra rich/etc. Also, because of slavery some populations in some groups are stuck at the lower rungs of the levels. Very few of anybody is at the ultra rich/top 1%. Education becomes a neutralizer. However, what you study is also competitive. Certain jobs have salary ranges and the increase in salary is based on experience, courses, education, awards, etc...
To be competitive in work america, pick a good major, pick a good school, pick a good department, get good grades, intern/gain early relevant experience, interview well, network well, present well, work well, take lead roles, play your role, take tough assignments, be there ontime, turnaround tasks quickly, ask questions, gel with the team, read the tea leaves, etc
Entrepreneurship is not for everybody, but what some make in year in a regular job could be made in days, weeks or month in a successful business.
people in this life can be if they have a vision, social skills and timing. Got to put in work though. Business school, internships, etc.
That's 400k a year? You're talking out of your azz.
