Why can't TNA compete?

[Impeccable]

This has probably been asked hundreds of times, but I don't watch TNA so I can't really say anything on the matter. However, I just went over to their website and saw their roster and it's pretty rammed with people, who if they were in WWE, I would like to see on a regular basis.

I know they can't really compete on a monetary basis with Vince, but are there any other things that is holding them back?

Bad booking? Lack of two hour timeslot? 6 sided ring? poor commentary team? What reasons apart from money is holding them back?
