I'm very curious when I see this stuff being posted on here.
One thing you can say equally for those who ARE rich, and those who want tax rises on the rich: they're both pursuing their own objective self-interest. The former want to minimise their donations to others, the latter are dependent on taxes to heal them when they get sick. We are in a long growthless period, so without taxes on the rich rising, healthcare for the masses must get shoddier and less well-resourced. It is obviously in their personal self-interest to agitate for more resources for hospitals from the only people in a position to provide them.
So two opposed groups, each following their objective self-interest.
But what about the third group? People who are economically in the latter group, but espouse the tax policies of the former. Anyone with an income below €55K, who have lottery-style odds of ever being in the top 5%. Social mobility is collapsing, so any thought that they will someday find themselves in the top bracket is increasingly ludicrous.
So why do so many of them campaign to stop taxes that will never, ever affect them?
Pure altruism? It's not that it's not in their interest, but that it's morally wrong. Are these people simply saints, people with contempt for their own benefit, but entirely committed to the well-being of the Other? Are these the kind of people who cannot pass a beggar without emptying their wallets?
