Those are specialized degrees and obviously require lots of time and of course the pay off is huge but doing some generic or pointless degree seems to be a waste of time and epically money to me. Actually Handymen/construction type workers earn more money than you think. There is a current shortage of skilled laborers and so demand has risen. These people earn serious money, even by backhanded tax free methods. So which is it? spending many years and ££ for a chance at a big payday or start small and build your life from scratch and have a sustained future.
