THE debate over social mobility was reignited last night thanks to an opinion from an economy-sized boy.

Boris Johnson, Londons six year-old mayor, said that stupid poor people are all stupid and poor, apart from the few that are surprisingly clever.

Boris said: “The poor clever ones should be allowed to be clever. But Ive counted and there are only seven of them, so all the clever schools will have enough room.

“The stupid ones will always be stupid and they should go to a thick school with dense teachers and write down all the wrong answers with idiot pencils.

“Then, when they grow up, they can do all the stupid jobs while the clever people do all the clever jobs.”

Delivering the Margaret Thatcher Lecture at the Centre for Policy Studies, he added: “So, what I am saying is, all the rich people are clever and all the poor people are stupid.

“Apart from the seven poor people who are not stupid.

“My job is a clever job. I get to wear a lot of different helmets.”
