Firstly as a retired teacher I find Angela Rayner more interested in education and the welfare of state educated pupils than many of the Education ministers of the last few decades. As has been previously explained, she is very aware of her own shortcomings and lack of education.
Secondly I have seen many teenagers with problems, some have turned to alcohol or drugs, some have been abused, some thrown out of the home for reasons that simply aren't their fault. People of our generations should know better than to make sweeping generalisations about those on the streets, based on nothing except what is written in the unsubstantiated articles of the right wing press.
