There's so much to this. As you at @soulman there are different business models, so comparing one to the other isn't easy. What it takes for one business to make a bat is different to others. Differing business costs, different locations etc will all make a difference. Some brands who have been established for a long time will charge more based on a reputation, whether that's justified or not is for the consumer to decide. Other brands less established, or in less affluent areas will have to charge less, but still enough to remain a viable business (whether they have pro's or not). In terms of labour, well there's another argument as some don't really have that cost as they will import and will still charge as much if not more than those who make here. No doubt doing so as they need to meet overheads and remain in business themselves.
With everything, there are choices to suit every budget, but I'd suggest it's definitely more expensive to make bats than it was, especially in the UK and that isn't down to just sponsoring pro's.
