What?

Most of those occupations you listed require specific knowledge gained precisely in school, such as law or medicine. Do you want a lawyer representing you that doesn't know the law, or a doctor treating you that never went to med school, because those pesky degrees "just exist to limit supply of potential workers"?!?

You see the effects of indoctrination-induced deep psychosis in many whose fear drives them into enraged action. When these folks read words of truth that conflict with their indoctrinated false belief, cognitive dissonance takes over.

See "Pete", whipped into frenetic action when he demands "How many degrees do you have Smack?"

Pete goes forth with a claim rooted in false beliefs -- "From an employment perspective, [a] University degree ... is ... a certificate that says you have attained a certain level of skills in a field."

No. A unversity degree says you have attained a level of indoctrination pushed by one of the many Churches of Academia.

Few departments of universities teach skills.

All teach ways of belief about how to look at and see the world, the earth and phenomena. Many of these ways prove fruitless -- Sociology, Anthropology, Social Welfare, Women's Studies.

You must earn college degrees to gain a job as a lawyer, accountant, engineer, medical doctor, dentist, college professor or government bureaucrat. This exists to limit supply of potential workers in said jobs.

One or two completed courses in remote sensing or operating system design hardly makes someone skilled.

From an employment perspective, University study can benefit in two other ways:
1) A degree (not a fake one) is essentially a certificate that says you have attained a certain level of skills in a field. So when industries have a 'skills' shortage, what do you think they mean? It doesn't necessarily mean lack of population willing to work. If we wanted an entire nation of skill-less dropouts then we'd have voted Howard back in.

2) Sometimes it can be hard to break in to a certain field of work at the base level, because companies may not have the time or resources to train you from scratch. That same company can have a pre-trained (albeit generically) employee who will be ready to work effectively in the short-term.

University = training.
Elite University = expensive training.

Unless you need licensure -- medicial doctor, lawyer, CPA, civil engineer, dentist, merchant marine, combat pilot, -- there is little call for anyone to attend a University.

You must earn college degrees to gain a job as a lawyer, accountant, engineer, doctor, dentist, college professor or government bureaucrat.

Yet, college degrees amount to nothing more than rites of passage in the Church of Academia, which allows you to join its Priesthood.
