The decision involves nothing less than the surrender of the taxing power to the moneyed class. By resuscitating an argument that was exploded in the Hylton Case, and has lain practically dormant for a hundred years, it is made to do duty in nullifying, not this law alone, but every similar law that is not based upon an impossible theory of apportionment. Even the spectre of socialism is conjured up to frighten Congress from laying taxes upon the people in proportion to their ability to pay them.
