Nope, it perpetuates elitism...If people are encouraged to privately educate their kids reducing the burden on the tax payer. It’s good.
That's bad because it means that the country is losing out on a lot of very bright poor kids!
Take Finland for example, their state system is so good that less than 2% go to private school. However these schools may have private suppliers but can't charge tuition fees, and are still state funded...
"Individual support measures are in place to guarantee that every pupil and student can reach their full potential. Differences between schools are small and the quality of teaching is high all around the country. The education system does not have any dead-ends which would affect an individual’s learning career"
But then education is a business in the UK, including the array of academies set up to make money for a few people and which often provides sub-standard education due to the practices they are allowed to follow!
