The answer to all of your questions is: money. Those at the bottom are making enough to keep a roof over their heads and food on the table. Those at the top are making tons and tons of it off power: oil deals, stocks, lobbying/corruption, etc. Those at the bottom don't make a fuss because they don't want to become homeless. Those at the top don't make a fuss because they don't want to die: if the powers that be are powerful enough to invade foreign countries, grab the president, hang him on live TV and then lie to the rest of the world about how he was keeping the country back while at the same time the country regresses back into the stone age (Libya, Egypt, Iran, Iraq) - what chance have you to keep your own head if you were to start blabbing about how things are unfair? It's all about money.
