>people can value something different than you (less government intervention, less restrictions on speech, lower taxes) for fundamental reasons different than yours //
You're right, but in the election run-up people living on minimum wage, who complained we needed a change because of the rich getting too rich, also were convinced that Labour's tax increases were a devastating blow to them personally; tax increases that a family of two well-paid professionals would be unlikely to even be affected by.
The reason they hate those taxes is not because they're bad for them, they would undoubtedly be benefited. Nor is it because they actually have a financial basis for a belief in lower taxes for the extraordinarily well off. It's a matter of advertising -- the private press splash an advert "Marxist Money Madness" or whatever and tell the people they're going to be hit by massive tax increases costing taxpayers 1000s.
Of course it's a carefully tailored half-truth. It does cost taxpayers _who_are_affected_ thousands but people on gross wages below £80k aren't. The message the minimum wage, or benefits only, households get is "if Labour get in we will have to pay thousands more tax" (which to them is a lot, despite the tax rises not actually applying to them). They also don't appear to realise taxes pay for running the country; things they benefit from (health, education, roads, trade relations, ...) or if they do that reducing taxes won't just make these things cheaper but mean they have to pay individually (and pay a profit to capitalists as part of that deal). If they do realise these things there's no rational reason for then to support them; really there isn't, not for the vast majority of the populous.
Many people can't do basic percentages, they genuinely just trust the headlines.
The BBC have failed in refusing to call out lies because that would be "targeted" at one particular party (apparently 80% of their Facebook posts were factually flawed) because they are the ones telling the lies.
And why? Well look at the headlines post-election many Tories made many hundreds of £millions. Everyone else is working on inputs to value creation and they're playing the system and walking away with all the value.
In short, yes, there are genuine differences in political opinion. But there is also a massive deficit of understanding too.
