Second, what is surprising is how many think the well off should not pay more. It would be fascinating to know why when simple economics suggests that this must be appropriate, since the wealthy have lower marginal value from each additional pound they earn or have as wealth than do those on lower incomes and as such can in economic terms pay more without suffering the same appreciation of loss from doing so.
To ask – more than what?
One question is should the wealthy – or the rich, the high income earners, whatever – pay more than those less financially blessed? Sure, why not, even Adam Smith was OK with a progressive taxation system.
A different question is whether they should pay more than they already do.
Entirely possible to answer yes to the first and no to the second.
