The quote above from Terpineol does indeed show how unsuited he is to practicing medicine. It also shows a laughably ignorant view of society, which no doubt explains his problems.
So firstly Terpineol, of course you'll make a decent living from being a Doctor. Less than 5% of the population earn above £100k. As an average GP salary is over £100k, you'll earn more than a decent salary you'll be in the top few percentile of earners.
Your attitude of sneering superiority above your patients, for their "abhorrent behaviour" would be funny if it wasn't true. If you think people are dull then it doesn't say much for your intelligence to choose a patient-focussed career
The joy and reward in practicing medicine is in the endless variety of people, their stories, backgrounds, attitudes and beliefs and how that links into the challenge of diagnosis and treatment. From what you've said I'd doubt you've even the ability of listen to a patient, let alone be open minded enough to empathise. When you pigeon hole everyone 'beneath you' as stupid, ignorant and the same no wonder the job appears unsatisfying.
Good luck in your alternate career!
