Really disagree with you.
If you are trained to do the job and pass the exams it does not matter how old you are.
Plus your comment about uni... People get into LOTS of debt going to uni and most of the time people go to uni and dont even know what they want to do afterwards and end up doing a job where a degree would not be a "must have"
Least with flying training you can be sure that people do have a goal in their head.
Please dont get me wrong I am sure that quite a lot of ppl going to uni do have an ambition that requires them having a degree, but not all.
