I think both the left and the right are to blame for this. The left's blame has been well-documented in the tabloids for the past few decades, I'm sure we all know the mantra - trendy teachers, lack of discipline, breakdown of "family values", "soft" prison sentences, etc etc. I would say the right wing cause has been the 'me' culture of individualism and selfishness that emerged in the 80s. Consumerism has made people utterly self-absorbed and inward-looking, no longer looking out for their neighbour, no longer possessing a sense of shared responsibility and respect for their neighbourhood, just a big two fingers to the idea of society.Just had enough of reading about lenient prison sentences and of peoples general attitude ... Too many people think nobody matters other than them, have no respect for anything or anybody, and too many people that can work but don't and just live off of the tax payer.
The big question is whether these are the inevitable results of socialist and capitalist elements of society, and what kind of interventions can get us back on track. I'm a fierce opponent of the death penalty for example and I think that liberal values (e.g. abortion, feminism, gay rights, openness about sex, striving for racial equality) and a decline in religious belief are all signs of progress, so I would never want us to reverse direction on those. On the other hand I'm also aware of a great gaping hole where religion used to provide an ethical benchmark, I see lousy parenting and insufficient control over children, I see mind-numbing trash and narcissism as entertainment and a seemingly endless path of dumbing down. It's a messy picture and whenever anyone tries to pin it on just the left or just the right, they're not telling us the whole story. A bit off topic I suppose but I think the support for Brexit is tapping into a bit of this dissatisfaction with the way our society has ended up - a feeling that the political class (the establishment, if you like) has let us down.
