I'll help you out, since you didn't understand the post, yet insist on posting like you did.
The 'top floor/top of the building' represents advancement in society.
'The stairs' represents the route to achieve advancement in society. At one time, everyone took the stairs.
'The elevator' represents a faster route for advancement in society.
The necessity of an 'elevator pass' represents the loss of equal opportunity in America. The time of everybody being allowed the equal opportunity of taking the stairs to the top with everybody else in America has gone. Now there's two routes: the broken down stairs for the underprivileged, and the 'elevator pass', for the few lucky ones and the children of the lucky ones.
It's all about EQUAL OPPORTUNITY, and the death of that principle in our country.
Like I said, you're out of your element.
