@parados,
I think this argument stems from Democrats desire to institute more progressivity into the income tax system, and they constantly complain of tax breaks for the rich and that the rich are not paying their fair share. They do this despite the fact that the top 10% income people pay about 70% of the income taxes and the top 50% pay over 97% of the income taxes.
I think the obvious point here is that more progressivity in the income tax tables is in fact a transfer of wealth from the rich to the poor, and if taken to the extreme, it would move people toward more equal wealth situations. The same principle would apply to inheritance taxes, whereby liberals want to take the wealth already earned and taxed, higher portions from larger wealth, so that it becomes essentially a transfer of wealth from those that have it to those that do not have it. In most cases, this transfer is via the federal government, as it collects the taxes and then redistributes the wealth back to society to various lower income groups, etc.
It is important common sense to understand the obvious fact that achievement of perfect equality of wealth is not attainable, but that is hardly a valid argument to dispel the obvious fact that some policies do attempt to move society toward equality, either by intent or by coincidence. For example, equal outcomes is not advertised as a goal of progressivity in the income tax system, but that is one of the effects if taken to the extreme. Usually, the justification for progressivity is based upon ability to pay or some such other argument that the rich reap more benefit from government programs or expenditures, which is hardly a valid argument, but nevertheless it is one of their arguments.
