Why should the tax payers subsidize Zuck's income? Imagine facebook has a $100 million profit. If it pays that to Zuck, the company then makes NO profit and pays no tax. Zuck pays income tax on it, but it's not double taxed through the corporation.
Thus, the tax payers are subsidizing Zuck's income.
I'm suggesting that in a society where only people who do useful things get rich, owners of businesses that have attained most of their value through exploiting network effects will not be extremely wealthy.
Thus, the tax payers are subsidizing Zuck's income.
