There are a huge number of people who have been ‘left behind’ by the rising inequality of the past few decades (the disenfranchised white working class being one subset), people who haven’t shared the benefits of a richer society but instead have become its victims, with higher house prices and higher cost of living, lower wages and insecure employment terms, poorer pension provision, etc. I would argue that these people do feel that they are victims and do want to strike back against their oppressors, if only at the ballot box.
This is where it becomes apparent that the phrase ‘capitalist democracy’ is an oxymoron. Capitalist societies, as we all know, are plutocratic by nature, and ‘democracy’ is a thin veneer. The rich control the traditional media, and are throwing huge sums of money into ensuring that they have effective control of social media, too. Their strategy is and always has been to deflect any blame from themselves, and instead make the common people fight amongst themselves. In the UK, they have been very effective in convincing people that the reason they have bad jobs and no money is not because society is set up so that the rich cream off all the wealth, but rather because foreigners are ‘coming over here and taking your jobs’. Most notably they have used the EU as a scapegoat, hence Brexit. I’m not as familiar with US politics, but I’m well aware of Trump’s wall to keep out those pesky Mexicans.
I do think that people care about being the victims in an unfair society, it’s just that they are misled as to the cause of that unfairness.
Having said all that, I’m not sure what the answer is, and how we ensure that when people vote, they are actually voting according to their own views that they themselves have developed, rather than as a superficial knee-jerk reaction to whatever the tabloid headlines or curated social media outrages impel them towards. How do we get people to think for themselves? And if we succeed, will we be faced by a new problem – the poor may vote for what they believe is a fairer society, but are they doing so out of self-interest in improving their own personal lot, or because they genuinely care about fairness and equality of opportunity? Difficult questions with no obvious answers.
