6th form does cost more and it would be hard to leave a 16 yr old who is legally able to leave school, without any money. Mine has a job, not sure for how long, but EMA is very welcome.
If they did away with benefits at 16 it would certainly put off some students continuing, but what's the alternative.
Worked out we would lose around £115 a week on a very low income. We won't because it won't happen in time. But many might if they start on our 16 year olds. Pales into insignificance compared to losing £33 at £45,000 salary,
with them all, shame on them.
