Scrap EMA and use the money to make tuition fees for maths and real sciences free
EMA pays students who don't want to learn to turn up and loaf around in 6th forms disrupting lessons for those who do want to learn. That's not value for money, it's a waste of money. If the savings from scrapping EMA went to encourage more maths, engineering and science degree students, which the country really needs then we'd be inesting in our future rather than throwing good money away.
Why does this idea matter?
Focussing investment where it benefits the country most.
