Why the fuck they can’t cop a house, the system meant to lock us out
But I’m knockin’ down the door, strapped up with a four-four

from J. Cole – Tears For ODB Lyrics on Rap Genius

Meaning

The odds are against those who are poor.
The system and institutions in society do everything to keep them in that financial status, for example denying them access to the same opportunities as the rich.

Some become complacent and fatalistic, however, J Cole is using “force” to get out of that lifestyle. This may be a reference to Biggie’s line ‘'Kick in the door, waving my four-four’' from the song ‘'Kick in the door’‘.
