In a closed pool, everything should eventually balance out again as the program rises back to where it used to be, since the rating formula is symmetrical. In reality, there should still be some deflation as slightly overrated players drop out and never give back their points. But the natural deflationary effect of new players coming in low and then improving would be slightly mitigated as they will achieve slightly higher provisional ratings than normal.
