I thought it was rather earlier than that – hardly a modern thing anyway.
Whether it is “modern” depends on your point of view. I suppose it depends on how long your memory is.
It is part of the trend in upping the level of general education required before you can take on a professional qualification. In both teaching and nursing the entry requirement used to be A-levels plus professional qualification. Now it is degree plus professional qualification.
In the context of this thread that means three more years study. Factor in the lost earnings as well as the 40k plus debt. Is that necessary? Are you really doing your job 40k+ betterer because of it?
Still, if it upsets you, delete “teaching” and subsitute a profession of your choice. Banking perhaps?
Would it be preferable for teachers to be less educated?.
Of course not. But you are confusing what is preferable to what is necessary and affordable.
And I think you are confusing being well educated (which i am all in favour of) with having a degree. 😀
