Some facts...
The people that win these shows are not "handed" a number one. In fact, they usually get the sh*t end of a rather nasty stick. Contracts that anybody with any sense would spit on, near to no say on the A&R side of their initial career and so on. You could compare them to circus animals. Yanked out of their natural habitat and forced to do dumb tricks for a dumber audience.
Besides that, hate or love the show, winning it IS hard work.
If anything they should be pitied. Most of them end up somewhere in obscurity. Only a few of them have been able to make the sort of career they wanted in the first place out of it and those are usually not the people that ended up winning the damn thing, since they aren't obliged to stick to the modern day slavery contract the winners get.
So next time you see one of them, pat them on the back and buy that copy of the Big Issue off them.
