Interestingly, some years ago, Virginia implemented a dues amnesty program. I do not recall all of the specifics. Basically, if a suspended Mason would pay up for one year, then all past years non-payment would be cancelled. The program was a success, and so many suspended Masons took advantage, that the Grand Lodge actually wound up showing a net cash benefit! And many Masons who had been suspended for NPD, got back into Masonry.
Illinois tried that around 5 years ago. Almost all of the brothers who paid the GL fee didn't pay their dues and a couple of years later were NPD again. The few it brought back were worth it to me.
