All of those should be a priority But for the Tories they are not and never will be, sadly.
And if each of those issues had a Marcus Rashford they would be higher priorities and higher up in the public discourse.
The reason why school meals is Rashfords issue is that he was a recipient of free school meals therefore personally passionate about the issue.
I also received free school meals for a time when my parents were struggling to pay the bills during the mid 80s. They worked hard and didn't waste money, but times were tough. I find some of the comments and attacks on parents on twitter appalling. Yes some parents are negligent but they are the exception not the rule.
