To me the song is coming from the pov of a poor man looking at the rich that rules the country. He sees their weakness and ignorance to the world. They shut themselves out because they know something bad is out there, but they just don't know what it is. The rich need the poor to do their work for them. Many buisness people abuse the poor for cheap labor so they may become more wealthy. "without us they will never make it" but. The song also says that they are equal. "they will never ever surpass us" it means that the rich are no better than the poor.
