I vaguely recall googling the topic some years ago. There is plenty of info. The 16th and 17th were, at the time, the Progressives’ dream come true. All subsequent abuses of our Constitution down to this day flow from the 17th.
Since almost all states had direct election of senators by the time the 17th passed, it gets too much blame. Repealing the 17th is still an essential step though.
