I really can't be bothered to read all the snowflakes answers on here.
I remember the school leaving age being raised from 16 to 17 and then to 18. That's right. In this century kids used to leave school and start full time jobs. They earned money and became responsible people. They didn't spend all summer dancing.
I had various 'pocket money' jobs from about the age of 14. From the age of 16 I worked part-time, all through my A levels. We all did. It was expected of us. We enjoyed it, we used to discuss our part time jobs. It gave us an insight into the real world.
I used to teach A level. My students were simply lusting after a part-time job, it was the holy grail. I also taught kids from Vocational subjects. Many of the older ones had part-time jobs, in pubs and supermarkets. They absolutely loved it. They loved having their own money. I remember 2 music btec students who were actually in a band and had regular gigs. They were earning as much as in a full time job.
Now for the harsh but true stuff. The only ones who didn't want or have a part-time job were wasters. They didn't want to do any work in college either. They had no work ethic.
Let's get even more harsh but true. Many jobs are disappearing. Shop work is difficult to get. Pubs are closing down. Employment laws make it arduous for employers to employ young people, especially part-time. The economy is struggling, we are heading for recession. Youth unmployment is at an all time high. The chances of your daughter becoming the next Darcy Bussell or Shirley ballas are about 3%.
If an employer has 2 job applications, both with exactly the same qualifications, but one has previous work experience and good references, he will take that one. However, it seems that your daughter is just aiming for a lifetime on benefits.
