Again people have to go back to core principles here. Why do professional sportsmen get paid? It is because they want a rightful share of the money that their labour generates through paying spectators and sponsors. If there aren't enough spectators or sponsors the players shouldn't be getting paid very much at all. If they are then the clubs involved have got their priorities wrong.
Is the Championship and Championship 1 ever going to be viable and self sustaining professional competition? I very much doubt it. It would be much better if the clubs in those two divisions stopped trying to emulate Super League badly and start spending their limited resources on more productive things such as developing young players and investing in their infrastructure.
People shouldn't get misty eyed here. Rugby League wasn't professionalised to liberate the working class heroes of myth it was professionalised because the Yorkshire and Lancashire Cup competition starting attracting large numbers of paying spectators and owners of the clubs wanted to recruit the best players avaliable by paying them money. Hard cash and economic reality struck home. 99% of rugby league players were paid nothing before 1895 and 99% of players were paid nothing after the split.
Up until the 1990s rugby league was semi-professional because the clubs couldn't afford to pay full time professionals because of the limited amounts of money the game generated. The same is now true of the Championship and Championship 1. Left to their own devices they wouldn't be able to sustain full time professionalism or any sort of expensive renumeration of players. You can't have the tail wagging the dog here. The Super League has the prospect of being an economically viable fully pro competition the other two divisions don't.
