Graveyard orbits are not the problem. Low earth orbits are the problem. Debris in LEO will be slowed by the atmosphere and will fall to earth naturally, but it will be dozens of decades for the higher altitude stuff and many dozens of years for all but the lowest altitude stuff. The only feasible way to clean this up that I’m aware of, really, is to stop making new debris and wait.
