Yes, there are les jobs than people employed, like all times, however there are Leo areas of the country and industries that are seriously short of people to do those jobs, with or without the need for qualifications.
What I find interesting is that there are apparently millions who can't get low paid jobs yet a significant portion of the people working in bars/restaurants in London are not from the UK.
If you can't find the job you want in your area then either find a different type of job or MOVE! Very little excuse if you are single, considering many millions do just at already.
Have you not considered that a student has less expenses & isn't protected by the minimum wage (which is why you see so many young people in restaurants/cafes).
