Its about the whole package rather than headline salary, working from home, holidays, pension contributions as well, FS firms would pay upto 16% pension and many airlines pay the minimum contributions and some paid 0 until law change recently.
From my experience aviation is the most competitive I have come across with the lowest terms and conditions and riskiest business model.
The benefit of Doctors, Dentists and Lawyers etc, you can become a partner/owner and own part of the business and command your own work life balance and salaries/dividends closer to 200k if you own the practice and the property the business sits in, being your own boss as you get older rather being given a non negotiable roster.

I think everyone would agree with this, dont do aviation for the 'high' salary, it will disappoint!
