&gt;No. When money is earned, that money is taxed. Society has gotten its share.<p>So income tax is the only just form of taxation? What about consumption tax? Property tax?<p>&gt; Zuckerberg is talking about donating assets that represent money in lieu of keeping it himself, which are above and beyond whatever income taxes he&#x27;s already paid.<p>Are you saying he&#x27;s donating after tax income? Or are you saying that it&#x27;s like he never had income in the first place because he donated it before it became income?<p>&gt;even if we accept that he should owe those taxes to society, then we have to reconcile that notion with the idea that society has chosen those charities to be considered tax exempt, and has effectively rubber stamped charitable donations as a societal good.<p>That&#x27;s true and I&#x27;m OK with that. I was arguing against the OP&#x27;s example of taxation as theft, not against the possibility of charitable giving tax deductions.
