And those aren't very profound "thoughts"
They are trivial strawmen.
I have never understood why it is greed to want to keep the money you've earned"
IF you reason critically about this statement - what you realize is that the core ASSUMPTION being made by Sowell, one he cannot back up - is the one that Ben Franklin eviscerates when he writes about ALL Property being an inherent creation of society
http://press-pubs.uchicago.edu/founders/documents/v1ch12s25.html
Private Property therefore is a Creature of Society, and is subject to the Calls of that Society, whenever its Necessities shall require it, even to its last Farthing; its Contributions therefore to the public Exigencies are not to be considered as conferring a Benefit on the Publick, entitling the Contributors to the Distinctions of Honour and Power, but as the Return of an Obligation previously received, or the Payment of a just Debt.
And Sowell's and Conservative's seeming inability to recognize this is the flaw in your ability to reason.
Similarly
but not greed to want to take somebody else's money
CRITICALLY REASONING about this leads you to recognize that Sowell is ASSUMING that taxes are a taking rather than a just debt to be paid to society. Sowell also assumes that supporting taxation to support a richer society is the same as deisre to take.
BOTH are flawed assumptions. The former is flawed in the same way as his assumption above. The latter the assumption that somehow one can have a society without redistribution of wealth being a core function of that society,
Thus Sowell is demonstrating either an intentional omission of relevant facts because of his attempt to argue his BELIEFS (there's that irrationality kicking in again - straight from religion) - which is what I believe he is doing
Or he is demonstrating outright mendacity - and I don't think he is outright mendacious, the evidence just isn't there
Or he is deeply ignorant - and again I don't think the evidence is there.
CRITICAL REASONING MATTERS.
Try some.
