What he is saying is …
When you give someone a finger, they eventually want the whole hand.
It is related to the law of One More Nerf™. Current people demand something, because they are needy. They will receive it and shut up. Eventually new people, later, will demand something (which is more, from the perspective of the old people), because they are needy. They were born into the “new” more, aka the status quo post change.
Or, because that paragraph was a trainwreck, in other words:
Old status quo:
People want a change and get it.
New status quo:
New people come and want a change, because they never experienced the old status quo.
It is a guaranteed downward spiral you drop in to whenever you give in to leechers, freeloaders, whining princesses and self entitled scrubs. The same argumentation is also used by the US of A when it comes to negotiating with terrorists, btw:
You give in once and they will demand more eventually.
