Anything but, the title literally states that social mobility in Florence is very low, and that capital is more valuable than labor. Bring back the death tax at 90%!

He is calling you a socialist, and implying that you are not normal.

I know and get that, he is an extremist that believes that the landed gentry deserve to rule over the landless serfs. I oppose that destructive policy, as it is a great way to stifle society as a whole and ensure we slide back towards the dark age.

Don't straw man his argument like that. I take it we both consider social mobility good for society. In that frame, defend the estate tax - does it improve social mobility? More than it costs? More efficiently than, say, a Georgist tax, or a basic income?
