Actually doctors start at 23k in 1st year BASE pay. They get a 30-50% bonus just for working more unsociable hours aka night shifts, there isn't even an increase in hours (officially though you work much longer than the "40 hours a week" they say you do).
In second year this rises to 28k. So it is very easy to get 35k salary in FY1 rising to 42k in FY2.
This increases when you enter specialty training and banding continues up until consultant level when you enter with a base pay of 75k rising to 101k after 19 years on the job. You also can get clinical excellence awards up to 75k as well as discretionary points from 3k-25k and distinction awards from 31k-75k as well as more minor bonuses for intensity up to 3k.
But if you look at the salary you can easily see a mid career 40s consultant earning 110-130k a year after bonuses and for the most well known successful and good at schmoozing consultant up to 275k a year.
Also don't forget consultants can go private, and plastic surgeons can make very high salaries.
The average doctor certainly makes more than the average lawyer. The best lawyers make more than the best doctors however, as you can see, doctors can work their way up as well.
If you are very keen, you can read this document, it has all the salaries listed including bonuses
