A poor man making £20,000 a year paying an effective 18% tax will get healthcare and university education for his children allowing them to become doctors, lawyers, accountants, engineers......whatever.

Our rich friend above and our poor friend above can both just up and send their children to Eton College at a cost of £40,000 per annum, or the University of St. Andrews at a cost of £30,000 per annum, give or take a few hundred pounds sterling.
Yay for equality! Everybody do the robot!
It is all down to academic performance. Not how deep your dad's pockets are.
Yes, it's
all down to academic performance. Because the Scottish guy making £200,000 can't and won't use his checkbook to give his kids the proverbial leg up, by sending them to fancy places like Eton.
In Scotland even a poor black man could become the head of the country. When will the USA ever be able to say that? 
Yeah, because "head of Scotland" is a job that it's in such high-demand... I mean luminaries as Dewar and Salmond have occupied this illustrious post! By the way, there's a difference between the Prime Minister, who is the head of the Government, and the head of the country, who is Queen Elizabeth II.
I guess that free education is a bit... shall we say lacking when it comes to civics?
