Fine sentiment but what about the good players in the lower leagues - If FFP does drive down players wages, (something that is debateable), then it will also drive the exceptional players out of the lower leagues, either upwards in the leagues or out of the country, again widening the gap between them and the EPL.
There is no evidence to support this. The Albion pay an average wage of £5,500 a week, players are unlikely to receive the same overseas unless they are signed by a top European club.
