Older workers taking jobs

Older workers taking the jobs while youth unemployment rises - currently 27.5% for those aged between 15 to 19 and 13.5% for those 20 to 24. What's going on? I would suggest that we should aim to reverse the process - progressively reduce the retirement age to 55 while increasing the employment rates of the youth. We should be extending the working hours, the life, the productivity and the efficiencies of our technologies and production lines.
