As long as your studying the congress of the 1890s, take a look at how many constituents there were per house member.
Congress people need large staffs to keep up with their overly large districts. The failure to have the house of representatives keep up with the growth of the general population turns them from the house of the people they were intended to be into out-of-touch elites.
Of course they do.
And America needs larger, even more intrusive government to help the sheep find their way into the pen.
