There seems to be an unspoken rule in Britain at the moment where is seems that no one can blame parents of any wrongdoing of their child. Knife crime rising (still no where near gun level in America before you start), blame the teachers and NHS frontline nurses for not checking/reporting it. Video game addiction, blame Fornite. Huge increase in mental health problems due to social media, blame Facebook.
As a teacher at a normal British comprehensive, the vast majority of these issues stem from poor parenting, but more and more blame seems to go elsewhere.
Saying that, we're also in a current situation with Brexit where not a single politician will ever say the words "the voters got it wrong and maybe we should deal with the underlying issues of why they voted that way rather than commit economic suicide", so maybe we just don't like blaming the root cause of issues because they'd be too hard to fix.
