It's a sad state of affairs, and in a way the richness of the Premiership and other bigger leagues with more marketing potential (TV revenues) is a direct cause of the demise of the Dutch league and other, similar smaller leagues. The youth academies of the big Dutch clubs are literally raided by the likes of Man City and Chelsea every year, who have their youth and reserve teams brimming with talent that for the most part will never get a chance in the Premiership because these clubs will just rather spend another 20 million than bring on a youth prospect. In the past these players would have developed in the Dutch league and moved when they were in their early to mid twenties, now they get picked up when they're 15 or 16. It would be better for all parties concerned if the big teams in the Premiership involved in a feeder club relationship with these clubs/academies and worked together to bring the talent on to the point where they were proven in the Dutch league (or at a similar level in other countries) before moving on to the next level.
Edit: as an example, I recently read the baffling fact that a team like Swansea earns more TV money than the whole of the Dutch league combined. When you consider that TV revenues is probably more than 70% of the income of most clubs, it illustrates the magnitude of the problem for the lesser leagues and it becomes self perpetuating because due to the lower level in comparison to the bigger leagues there is even more incentive for young players to move to bigger leagues (too) early.
