And shame on all the people on here who say that people are destined to remain in the same class they were born into. Everyone in this country has the ability to excel. I doubt all these Apple execs were born to "rich" parents, but they're doing just fine now. Look at most immigrant families sacrificing their generation just so their child can get a U.S. education.
Joke post?
Nobody said that everyone is destined to be in the same class in which they are born. Your post reeks of naivety. Not everyone in this country has the ability to excel. People are born with different strengths and weaknesses (biological mutations, etc), and some are just not smart enough to create vast wealth for themselves. They are destined to live paycheck to paycheck - working for someone else. I believe I already said this earlier: Most people will remain in the economic class they are born into for their entire lives.
A more defensible position for you would be to say that the country provides ample opportunity for those with the skills, initiative and ambition to succeed (with appropriate connections). Notice, not only do you have to have the innate skills, you have to recognize and take advantage of the opportunities that present themselves, or rather, go after the opportunities.
And the point you raise about Apple execs is a statistical fallacy. You completely ignore the vast majority (thousands) of engineers that graduate from MIT, Stanford, U Penn, etc, who fail to find decent employment, and the many thousands more who do find employment but never make it to the upper echelons of wealth. Think of it like evolution, we can all look at the vast amount of extant species we are familiar with and think "Wow, there are so many species, it's probably fairly easy to survive and create offspring". Yet when you look at each species individually and follow their ancestors back through time, you realize that there were hundreds of thousands of cousins of that extant species that went extinct through the ages. Only a very small minority actually survived to pass on their genes, even though all technically could.
