I am glad you did not turn that political. here one reference I searched for: The liberal professions can be characterised as follows:
they provide intellectual services based on a specific professional qualification or skill,
these services are provided personally and are based on a relationship of trust,
the activity is carried out autonomously and on a professionally independently basis,
the liberal professions are characterised by a professional ethos, they have an obligation to the contracting authority and are required to act in the public interest,
and they are subject to a system of professional organisation and oversight. Health care professions: Doctors, dentists, veterinarians, medical practitioners, physiotherapists, midwives, massage therapists and qualified psychologists.
Legal, tax and business consultancy professions: Solicitors, patent lawyers, notaries, auditors, tax consultants, tax agents, advisory general and business economists and chartered accountants.
Scientific and technical professions: Surveyors, commercial chemists, architects, pilots and experts.
Cultural occupations: Journalists, press photographers, interpreters, translators, scientists, artists, writers, teachers and child care workers.
