Happens in every league, unless strict wage and number of player limits are brought it, it will continue to happen. Scottish clubs had their chance over the past decade to try and step and fill the void left by Rangers demotion, no team could do it. What that did was allow Celtic to be come poorer and still walk the league and cups every season this the entire standard of the league dropped. Unfortunately due to the existing fan bases and world wide interest in the old firm nobody will compete without serious external investment.
