I agree. Taxes are not necessarily a violation of inherent individual rights, though they do become immoral when spent on denial of rights, such as abortion.That is true, in as much as the common good should not come at the expense of unjustly depriving any individuals of their inherent human rights. But after that condition has been met, there still remains the possibility that some individuals will not like what is decided for them, such as the raising of taxes. That does not necessarily constitute the denial of inherent human rights. And therefore it may be a valid expression of the common good.
