My DD has a degree to be an allied health professional... why does she need a degree?
Because of the level of knowledge and ability to put that into practice that is required.
My Mum was a nurse and midwife, she didn't have a degree, she didn't even have the equivalent of A-levels, she was blown away with what my DD needs know (the reports she has to write, the H&S, the safeguarding) and is required to do, on top of huge responsibility.
Stuff my mum never had to do...
On a practical level, there is not enough exp staff to mentor all these students... when my DD has a student on placement, her workload ie patients she sees, drops by 50%, sometime these students require handholding to the nth level, her workload drops even further.
Degrees are needed for HCP and AHPs the world over, very few countries do not have degree entry.
With the greatest respect, the world has moved on in the last 100 years
