There will always be work for vets and their assistants. Not necessarily for a load of teachers. Covid19 has alerted people to the fact that learning can be online, for children and for adults.
That also raises the doubtful advantage of 'doing a degree' as it was done when people wrote with quill pens. A juvenile notion of what is interesting can be mistaken, and certainly it is impossible to be sure that most professions or occupations can be learned once, then practiced for life, without further training throughout life. Even lawyers can be replaced, to some extent, by A.I. In any case, their knowledge will become outdated with each new bit of caselaw or legislation.
More realistically, expect to try different areas of work as soon as possible, to learn at the same time as working, to change and re-study as often as needed. It is inevitable that the curriculum for any old style degree will be outdated fast. Modular units, mainly studied in private time, and on-line, will be essential.
Once upon a time, someone could be an apprentice blacksmith, certain he had a lifelong income, because every village needed such services and skills. How else would they get their horses shod? Horses were the only transport. Then, someone invented cars, and soon those smiths needed to sell petrol and learn to mend engines.
It really is long overdue that people stopped the traditional way of thinking about 'going to university' . It is just as stupid as continuing to believe there is no other method of transport apart from horses.
