How would you explain the clause in Article 1 Section 9 that says, “No capitation, or other direct, tax shall be laid, unless in proportion to the census or enumeration herein before directed to be taken”? I am having a difficult time explaining it to others. Also, from how I understand it, would that make the Estate Tax unconstitutional? As well as Obamacare’s individual mandate that the SCOTUS accepted was a tax?
