To work in Europe you need at least a MEng.
A BSc none acredited Aerospace degree really doesn't cut the mustard. In the UK aerospace is towards the bottom of the Engineering league on pay scales.
Oil and gas, Chemical, Nukes, Electrical, Civil all earn more.
I think the average graduate pay for an Engineer is 23k.
Optician is on 35-40k straight away.
And Pharmacy is similar.
Both you can do Locum work as well pretty easily.
