Sure, but you can do many uni courses part time and still work full time which is almost impossible with trade apprenticeships.
I realise there are massive logistical problems with part-time apprenticeships that probably make it impossible to offer them, but it's a factor when considering a mid life career change if the choices are 1. plod along with a degree part time or 2. throw in everything and go back to teenage wages for four years, which is difficult with mortgage/family etc. I know people do it and full marks to them
, but it's a big call to make.
