You can go into just about any generalist grad scheme with any degree, including a law degree. Also pharmacy does not guarantee a 60k a year job at all...I think you are suffering from "the grass is greener" syndrome. Worth bearing in mind on reddit certain forums used by medics bitterly complain about how much better paid their peers who did law degrees are than them.
If you have a genuine interest in and enjoyment of teaching younger students then go that route. Why do you think it's "lesser" and not "worthy" of your grades or degree? Someone has to teach the future generation, is that not an important enough job? Societally most would consider that far more important and worthy than working as an investment banker or corporate lawyer. So some of the issue might also be with your somewhat elitist attitude regarding work and degrees. Which isn't going to help you no matter how much you might want to convince yourself otherwise.
Also recognise also that in most areas of the UK, before the current cost of living crisis, the amount needed to live comfortably was less than £60k a year for a new graduate - in fact it was less than that for a mid career professional. Studies have also shown that earning more than that generally does not correlate to increased self reported happiness or life satisfaction. Money can't buy everything, and living in a smaller town in the midlands and doing something you love and having a comfortable salary while doing it is going to be much more rewarding than earning oodles of money doing a job you hate spending 2 hours commuting to London every day and working twice as many hours.
Talk to your personal tutor at uni, talk to your GP at your GP surgery, and well...get on with it. Get the 2:1 degree to tick the box that every graduate needs and grind through applying to grad schemes, which need not be legal training contracts. I guarantee you that you will begin to realise there is more to life than than the number of digits in your paycheque if you can keep a roof over your head and the heating on with some spare money left over. There's an entire psychological theory about it in fact.
