ELI5: my rent keeps going up but my salary does not, what is the societal expectation or gain?

Are poorer people supposed to move out every few years so the wealthy can move in? Is this some sort of "step" in gentrification? What happens when all the neighborhoods are gentrified?
EDIT: I worded headline poorly. My bad. TIL: there will always be poor people and we will always live somewhere- not gonna fret about it anymore.

Christ said, "The poor you will always have with you."  You need not worry about every neighborhood gentrifying.  By the time the last ghetto is turned into chic lofts, the chic lofts of today will be the ghetto.

Generally speaking the only thing your landlord and your employer have in common is you.  Your employer will pay you what he thinks your work is worth to him, and your landlord will charge you what he thinks other people would pay to use his property.  

The way they find out they are wrong is by you mentioning it to them, and if they don't change, you leave.  If you don't leave, you are proving that they are right.

There is no guarantee for rents or wages outside of minimum wage laws and some cities with rent control ordinances.
