The founders did not envision a class of professional politicians or the dilution of the vote via inflation of the representative ratio. As I've
pointed out elsewhere, Article 1 Section 2 of the Constitution states "Representatives shall not exceed one for every thirty Thousand,..." which sets the maximum number of Representatives based on population. Until 1911, when the current number of Representatives was frozen at its current 435, the number of Representatives was increased, though not enough to prevent dilution. Since then the dilution has accelerated to the point where Representatives are anything but representative of the vast swaths of population they purportedly represent.
That is the root problem at cause of the current issues of undue influence in the political process.
