Earlier quoted context omitted.
Unpacking the whole context and philosophical debate (e.g. between libertarians and Marxists) requires a book-length argument. (But to briefly answer your question, no. “People ought to be entitled to what they create” is not a universally accepted principle.) So folks responding to Graham are mostly not going to do the topic justice. (Side note: In a similar but less defensible way, Paul Graham’s summary of Joseph S…
> “People ought to be entitled to what they create” is not a universally accepted principle Yes, in the society and economy we are discussing this is a universally accepted principle. Bob is a farmer. He has the same amount of land as his neighbor, but he works twice as hard, and grows twice the number of crops to sell in a year. He has twice the income. No one would reasonably claim that he's entitled to none of wha…
But in the real world we are not born equal and we do not have access to the same size of 'land'. There are differences, sometime vast in family wealth, property, health care, education and access to nearly 'n' number of resources. Bob may be born with the land and have 'n' amount of time and the luxury to think of things like productivity, wealth, interests, life while Tom may struggle his entire life just to survive or maybe work towards getting 1/10 of the land as his entire life goal.
Moving to the real world property taxes are not fixed on income. Income tax is an entirely different tax that Bob and Tom would pay based on their income irrespective of their land holdings. If Bob is more productive he would pay more tax but I am not sure income tax or 'simple productivity' as a concept is useful to understand or explain inequality and disparity in a world where everyone does not have the same piece of land.
