You lack da vantage point that most people feel we dont have that "American Exceptionalism" posture anymore.
This country subscribes to individualism.
And greatness starts by letting individuals aspire for as much as they want.
Why hold yourself back? Eff that. let's be great.
You can aspire all you want but capital still matters.
Let's look at our own history and put aside race and racism. Let's just look at white people liking under different economic conditions.
Settlers in most of the South had to started their economic lives in debt because the land was owned by very wealthy absentee land owners who lived hundreds and even thousands of miles away. In places like Minnesota and Wisconsin, settlers did not have to go into debt (to acquire the land at least). The reason was because of the North West Ordinance and the Homestead Act, basically a big government land giveaway for those who were willing to work the land.
Centuries later, white people in Minnesota and Wisconsin are much wealthier than the average white person in Georgia or the Carolinas. I am sure that white southerns aspired as much as German settlers in the upper Midwest but their generational wealth ultimately hinged on the terms of how they acquired their land.
