Why do you think people are unskilled? Do you believe it's a lack of personal responsibility or a lack of opportunities? And what types of jobs and industries are you classing as unskilled?
It's a genuine question asked with sincerity. I ask because accountants, paramedics and organ transplant workers you mentioned are most definitely not unskilled in my opinion. I've met hundreds of people in warehouses, manufacturing/engineering, waste disposal and countless other industries of all levels from directors to cleaners and there's very few who I would class as unskilled, if any. Those who haven't got the physical capacity or ability to learn and develop new skills are even fewer. Whether those people actually do anything about it is an entirely different matter in my opinion.
Btw, I'm not including the millions of people who are unable to work or who have genuine learning difficulties, as a nation, in fact all over the world I don't think we do anywhere near enough to support those people. I'm only talking about people who can physically work and have no genuine learning difficulties or personal circumstances restricting them (e.g. kids who are carers for parents).
