The author of The Migration Period blog proposed that very few people actually care about taxes as such: whenever they protest against their taxes, they basically mean that they disagree what their taxes are spent on.
Two minor disagreements first:
1) I think most right-leaning people disagree not as much about spending them their taxes on poor people but about spending their taxes on fat bureaucrats who pretend to care about poor people.
2) Even with taxes spent for the best possible purposes, one should’t really want too much of the GDP spent by a government because that means central planning and you know how effective is that. Keynes, not exactly a hardcore libertarian, guesstimated the healthy upper limit of sanity at around 25% of GDP.
But what I would really like to point out is this: I think it also matters how things are communicated. Why is it so that in the USA welfare is always communicated as the rich helping the poor, while in Germany welfare is always communicated as citizens buying services from the government for themselves?
