Folks that own a vast amount of stock do not pay taxes on that stock. They own the shares, and they take out loans against those shares. At some point they rollover or pay off those loans by selling some shares, but the shares have increased in value significantly in that time, or they’ve been granted new shares.
When we say “<business> has created value for shareholders”, it’s said in a way that implies that somehow that wealth creation makes its way into the tax system by virtue of the fact the wealth was ‘created’. It does not.
