The purpose of the entire government is for it to be very slow to act. The founding fathers knew that the Constitution was never going to be enough for all future generations, but at the same time, they wanted both houses and the President to counterbalance one another so that most bills ended up in defeat.
I don't think that getting rid of the 17th Amendment will do anything to promote that cause.
