Exactly it's all about self interest & not a left/right issue. How do you think we can challenge it?
Keep speaking out and sharing. Challenge the media narratives. Use evidence - particularly from government reports - against the government. Ask difficult questions. Put yourself out there. Stand in local elections. Think about becoming politicised yourself and challenging politics from within (includes public service and within the private sector not necessarily just in politics itself). Educate and explain the importance of accountability as much as possible.
I do think that Leavers and Remainers in large part have huge common ground here.
One of the big drivers of how people are voting is out of a sense of frustration about 'elites' and how they treat ordinary people with contempt and line their own pockets etc etc. And how they are not held to account.
To stop the divides in our society right now this is what we MUST do. Focus on this common feature.
Sadly, this is what upsets me, as May presents herself as somehow being this person - against the wasteful EU etc etc. Against the 'elite' experts and institutions who oppose her dressing them up as 'enemies of the people'. It couldn't be further from the truth.
There are also huge problems with educated people in the way they talk about things and try and convey this to less well educated that are being exploited in this. If often comes across as being patronising or confrontational, so its something that anyone in that situation has to be mindful of.
The thing is here; we are ALL seeing the same thing, but the way we are interpreting it is different. Some people are being led in a particular way because of this media narrative. We have to offer and alternative credible explanation and allow people to ask questions of what they are being told themselves, rather than telling them they are just wrong in blunt terms.
