You are right that Congress are the immediate legislative agents, but the Congressional responsibility is back-stopped by the people, because ultimately (with the exception of impeachment and removal from office, which is asking the legislature to police itself) only the people can decide to stop supporting them. And you're right about the 17th Amendment, but that's in the past; modern American voters have more power to choose their representatives than they have in most of American history, and they do not exercise it.
I don't know who else's fault it can be but the electorate when they saw how the current President operates and re-elected him. To say nothing of re-electing the same Congress over and over despite that body having a sub-30% approval rating.
... and if the people don't hold the responsibility, what would you recommend the people do? I'm not sure what "a notion of jurisprudence" means in this context: are you suggesting replacing he power-at-a-distance of an unpopular legislature with rule by nine unelectedlife-appointed officials and their underlings?
