Sir Roger makes an excellent point. Young inexperienced first time job seekers are being priced out of the market. Sure no one wants to stay on $10/hour for long, but hell if it will get you your first job, it is worth so much more than that as you then get actual work experience.
I started work at 12 as a paper boy and occassional dairy assistant. At 14 I was working every day after school. There is no way I would have got those jobs if they had to pay me full adult wages.
The massive increase in youth unemployment is partly because of young people being priced out of the market. And sadly, Labour wants to make it even worse – they want to make it impossible for any young job seeker to take a job for under $15 an hour.
