This comes from George Orwell's book 1984.
There are 3 classes of people in the world (bottom, middle, and top).
The people at the bottom struggle every day just to survive, eat, and pay bills.
The people at the top hold most of the wealth and power and strive to hold on to it.
The people in the middle want to switch places with the people on top.
This is human nature. And this is why I'm cynical of anyone advocating for _________.
I know it never stops there. Any group of people who do gain ___________ will not stop there.
They will keep pushing forward for more and more. It is human nature.
