First you live in Sydney so how much wear would you get out of a Peacoat?
I get a lot of use out of my Peacoat but then I live where we have a real winter.
I would agree that wealth inequality is a driver of dis-satisfaction, but I think it's disingenuous to attribute that to modern institutions. Britain has always been an incredibly unequal society - it was feudal and the industrial revolution and the 20th century haven't really changed inequality that much - life is better for everyone, sure, but the landed gentry are still the landed gentry. There are areas I pass every day that some old bloke owns and will always own as long as he passes it down through the family.
I think that neoliberal economics has not really worked, but I think that dissatisfaction should be placed at the domestic government for curtailing public services and funding public programs. The austerity measures have real effects in schools, in workplaces that train young people and in community support programs. Certainly a shrinking economy/foggy outlook caused by Brexit could lead to further cuts. Which I think is also an indicator that the government, here, has not abdicated sovereign fiscal discretion.
Additionally, the governments have not tried, or have failed abysmally, to curtail cost of living. This is perhaps not such a big issue as it's out of control in the South, which is also more prosperous, and the North East is really the area that needs the most re-vitalisation (having relied on manufacturing and mining which have declined substantially). I certainly don't have an answer here - perhaps a good place to trial UBI or something similar.
The EU seemed to me to be a relatively protectionist organisation: keep things within Europe by making non-European imports more expensive, subsidise key industries such as farming in order to support those industries. Perhaps I'm wrong here, though. This is my most tenuous point, though, so I'm very open to this being wrong.
So, I do not think that the poor are directing their anger towards the right groups. There have been consistent failures of government to do anything to ensure a sustainable and meaningful standard of living in the North East - Orwell wrote about it in the 30s, obviously the 80s was a rough time, and we can see now people are angry. Disenfrancised lower class white people are a serious cultural issue in all parts of the Western world. People who relied on good, stable jobs without much education or pre-honed skills have been surpassed by faster, cheaper and more malleable labour elsewhere.
This is a huge issue at home, in the UK, in the USA. Unfortunately these groups often turn to immigration or globalisation as the source of their problems, rather than corporate greed (CEOs making multi-million dollar salaries while laying off workers), privatisation (which means tax payers cannot prop up industries with the intention of ensuring impoverished areas have income and stability) and short sighted governments failing to re-skill areas that will obviously need it. These groups are also incredibly susceptible to nostalgia because, let's face it, life was better for them way back then. It just also means the past becomes a narrative that anyone clever enough can seize and twist - which is where the nationalism, xenophobia, etc come into play, IMO.
This also ignores the fact that as problems become more global only global solutions are adequate.
Apparently there are good arguments for leave that are not related to either points. Which I think is entirely possible. They just weren't the points most leave voters cared about.
