I do agree rubylady that some of the presenters are getting ridiculous amounts of money but, much as I dislike shows like Top Gear, they - and their presenters - are popular.
If the BBC is going to continue to produce progammes with mass appeal, such as Top Gear, Strictly and The Voice, rather than concentrate on minority interest programmes, then to some extent they have to compete with the commercial channels for their presenters. Like many people, TV presenters want to be paid the going rate and, in the main, are not likely to forego the top money that commercial channels and work for the BBC instead.
If the BBC's range of programmes becomes more "niche", fewer people will watch it and I believe that will then provide the required grounds for getting rid of it.
I really don't understand why some people say there is nothing of interest or quality to watch on the BBC. There have been some fabulous one-off dramas like The Lost Honour of Christopher Jeffries, Marvellous, etc., some great series like Happy Valley, Last Tango in Halifax, Spooks, Silk, etc., and a host of light entertainment and quiz shows, current affairs, consumer information and documentary programmes - surely something for everyone?
And, of course, BBC radio adds yet another dimension.
