Does this just mean that we should adopt a "progressive" tax system? (i.e., top 1% would pay disproportionately higher amount in taxes than the bottom 10%, and so on?)I think a better idea is fixing the income tax calculus.
Of course we already have that to some extent, I just don't think it's progressive enough. For example, a big part of each low earner's taxes (here in the US, anyway) are payroll tax, which is regressive, the exact opposite of what's healthy. And the capital gains rate is flat and very minimal, which also doesn't make much sense for the economy. IMO changing those two things plus making the income tax more progressive is a better idea than a land tax.
wealth is usually distributed in a power curve so so steal the Forbes "fair" tax easy function.
the tax code should look something like this. tax = ((income ^ p) - standard deduction)/n were 1 < p < 2 and n is somewhere around 5.
